Hope that might help. Good luck!!``~

Again, why i'm not a hydro guy.

Thanks hatch, I just changed all the water in my tub last night, didn't clean it as it doesn't need it and I can't really do that until the grows over. Theres no scum at all inside, all is good there. My nutes ended up being 150ppm @ .5 after the change, I'm going to take it up to close to 200ppm as I need to add a bit more water. Does that sound like a good number for now? My last grow I had the ppm at 950 @.5 late in flowering with no problems but I have a feeling kali mist doesn't like to much nutes, I guess no plant likes it at 500 to start out with though. I guess I seem to think if the nutes are higher the plant will grow quicker.

Hey Don I'm hoping to get my PPM up to 800 @.5 later in flowering, that would fry them right now though. The hydro thing is super easy, I'm having a bit of trouble because of my own laziness. I should have dumped the water as soon as I saw a brown spot but I left it for a week to fry the plants and I think they stored up nutes in them which kept it burning up itself. It was at the point where I should have maybe had my growing privilages taken away, abusing them like that, but now I'm giving them all the attention they deserve.

[HATCH]

It's alway's better to be low than high on the ppm. Just watch your plant's, they will tell you if 200 is to high or not.

Ya Don it's not really that hard. You just have to stay on top of your water. If you let it get dirty you are going to have problem's.

Good Luck!!!~~~!!~!~!~!~!~~

Well after my water change 2 days ago I had the ppm at 175 @.5, yesterday it dropped to 150 and today down to 128. I'm pretty sure that means the plants are using up the nutes? In a couple days I'll take it back up to 200, there quite mature now and should be able to handle it. Growth has been great over the last couple days and I think #2 is ready to be cloned now, I'll probably do it tonight if I get the bubble cloner done, wish me luck on that one! I have a few pics below of what I believe is a good clone to take from #2, do you agree? Thanks for all the help folks!!

that box is pimptight man, really nice setup

Thanks Joker!

Well as most of you know I've been growing a couple kali mist plants for about 56 days from seed. There in a DWC tub and I'm using the Lucas formula for feeding, (General Hydroponics FloraBloom & FloraMicro) When I started I had the nute level way to high (500ppm @ .5 conv) and I burnt them up pretty bad, after that I changed the water and had it at 150ppm @ .5 for quite a while, just a few days ago I took it up to 200ppm and now its at 220. At this point it looks to me (very unexperienced) that they are nute deficient now, does that sound right? If so what do you think I should be doing at this point? I'm going to be cloning them this weekend and then switching to flowering in a week or so, I have no choice, I've been waiting as long as I can for them to get healthier. Here's a bunch of pics, any comments would be great. Oh yeah, I also can't keep the PH stable, some nights it will drop to 4.4 other nights it will go up to 6.2, I have no idea why. I try to adjust it to 5.6ph.



Plant #1: This one got burnt really bad, I've removed as many leaves as it has over time.


Plant #2: Didn't suffer from nute burn so bad, it didn't grow at first because of heat stress, almost died one night, but it also could have been because I kept the rockwool cube to damp at first, either way its nice and bushy.


Is that nute burn or nute deficiency?












This is one of the top leaves on #1.

[Extracurricular]

im the worst person to ask about deficiencies and such. so i cant help there. but im glad theres a couple more updates. i had No idea you were going to veg these babies for that long. dont you have a pump connected to your DWC system? put a few drops of ph UP/DOWN and turn that pump on. let it circulate for a minute before you read it. and also, put the pH up/down in after nutes. but you probably already know that. are you putting a screen over them soon?

[HIGHDRO]

First of all... Rob... great box design. I'd love to emulate it in my next project.

Here's something that might help you with your Plant Sickness: http://forum.grasscity.com/sick-plan...ems-guide.html

It really seems to me you have a pH problem because of the yellowing. Yes it is a "nutrient" problem, but only because the pH is probably either too high or too low and it is basically locking out the nutrients it needs (Nitrogen, Sulphur, Magnesium, etc.). What you basically need to do is get that pH between 5.5-6.1. Hopefully you have a pH checker... so just stick it in the drained water and take a good look. If it is too high, drop a little bit of lemon juice and check back in an hour or so. If it is too low, drop a little baking soda in the water and check back.

Otherwise it looks great... other things you could do to maximize output:
LST (Low stress training). You have a LOT of leaves despite your stunted start. Strings pulling the main stalks apart could help get light to more of the plant. You also might want to take a look at a couple of trimming guides... yes leaves are good for the plant, but if they prevent more growth than they add... then it can be a problem. -SUSCRIBED

Hey Extracurricular, yeah I had no idea I was vegging this long either, its killing me that I haven't switched to flowering yet, these suckers better be females or I can't be responsible for what I do to them. Still probably over 3 months to go. I do have a pump inline and I'm always adding PH up or down, I'm glad that works well but it just won't stay stable, not even close. My last grow that wasn't an issue but this time it always goes far past the recommended levels. Why o why o why, is it a design problem, does kali mist not really like hydro or is it me. I do have a screen basically ready, I'm going to put it in there right after I clone and then switch to flowering a week or so later. The clones will be done in a bubble cloner and then these ones will go into perlite and hopefully one will be the mother. I'm guessing at this point the plants already know if there male or female, at least #1?

Hi Highdro, glad you like it, the best thing about it all is the wheel for moving the light up and down, I highly recommend it. I think your right, my problem likely is PH related. Like I was saying I just can't keep it stable, 24hrs later its always way off the scale, one way or the other. I have a decent pen and I know its working fine. I guess I'm just going to have to check and adjust it more often, I seen an automatic PH adjuster on here somewhere, I could use one of those now. I do have #1 tied down a lot, can't really tell in the pictures but if it wasn't tied down it would be another 6-8" taller at least. I do plan to trim lots this grow, I should have done that more on my first but I think its ok bushy right now as I need clone, I'll be taking quite a few to get these things smaller, don't want to run out of room in the box. Well thanks for the info, definitely helped.

A few other things I wanted to mention. The smell is quite strong already, just about as strong as my last 2 when they were done! Yeah I'm a little worried about this as they haven't even thought about budding yet. The other day I thought I better fill up my filter with activated carbon to see if it even works, I'm happy to say at this point its perfect, all smell is completely gone until you open the cab. I really worked on packing the carbon in. Something very strange happened right after I filled it up. Besides being worried about it working I was worried if my 4" vortex would be up to the task, with the filter empty my temps were 80 - 82f and the filter would not hold a piece of paper like my odorsok would. So my fear was what's going to happen when I fill it up with carbon, no air will go through, seems the opposite has happened. Immediately after filling I noticed the box had a lot more vacuum, when I went to close the doors it sucked it shut, never did it like that before. There's enough suction now to hold both doors closed on its on, thats pretty damm good as the rubber seal pushes it open, it couldn't even think about doing that before. Next day when I opened the cab the temp was down to 76f the same as my bedroom, it has never been that low and has been there since the carbon went in. Am I the only one to find this a little strange? Another thing thats getting better over time is water temperature, its get lower but that was kind of expected. At first I didn't cover the black bucket and the temp got up to 88f or so before I covered it with mylar. After dropping the temp with ice it went back to 75f and stayed there, quite a difference. Now that the plants have basically covered the bucket it down to 69f, I think thats pretty good. Well enough rambling or no one will read all this.

Hey Rob I'm just tuning in on your grow, nice setup you got there and beautiful plants!

I was reading your last post and the first thing that caught my eye was how you were talking about your unstable pH as well as high water temps. I'm having similar problems with my grow and you really need to be tough on maintaining the pH between 5.3 and 5.8 or the nutrients wont soak up. I think 200ppm is pretty low for plants as big as yours so you definitely have deficiencies going on. Nute burn usually starts at the tip of the leaves.

Anyways, try to keep your pH stable and raise your ppm consistently for the next few days to see how much they can tolerate. Another thing you know you need to watch is the water temp, if it gets too high it promotes algae growth and root rot, another problem I have had in the past. Root rot is not fun. Hope anything I said can be remotely helpful. Hope these babies turn out to both be females! Good luck man.

[RobsGreen]

Hi hwhobbs, glad to have you around, great advise too, thanks very much... Based on my last grow (1st grow) I don't think water temp is too high right now. Last time I was around 75f and everything went very well, no rot or scum at all. I only had it in the high 80's for a few days, no roots were around then, its been 75f the whole time basically and now its at 69 which I've never had. What is your temps? I thought 200ppm was a little low, at least based on my last grow, I had it at 600 or so by now. Do you think 400 would be a good number to aim for now or 500? I need to add some water tonight so I'll take it to 300. One thing I noticed in the last 48hrs or so is the ppm level hasn't dropped. When I had it at 150 and took it up to 200 in 24hrs it went down to 175 and 24hrs later it went down to 150, doesn't that mean that plants are taking the nutes? Thanks again for the help man!

[AugustWest]

great cab design man, great bucket setup as well! Looks like the issues are behind you. Best of luck w/ the flowering.
i don't do hydro, but yeah if the PPM goes down, then they're sucking up the nutes. That may or may not effect the PH as well, so keep an eye on that (i'm sure you do).

gl man, peace

[RobsGreen]

Thanks AugustWest, yeah I hope those issues are behind me soon. I'm giving them some love right now and for the last couple weeks I've been looking for any signs of pre-sex. I've mainly been watching #1 as its more mature but just now I found something that makes me quite confident #2 is a female, #1 also looks like it might be too, certainly no signs of any nuts. Here's the proof.

Plant #2: Day 57 still in veg 24hrs light

[AugustWest]

btw man, those spotted leaves look like you had some PH swings in the past.. as long as it's not spreading then i wouldn't worry about it.
gl!

[RobsGreen]

Yeah I've had quite a few big swings, I'll try harder to keep it under control. Its hard to tell if its getting better or not, I'll report in a few days.
