This time I purchased clones, I did not start seeds in rockwool, the clones came in the peat plugs and i put them directly into the hydro set up. I'm probably going to take 3 out and move them to a simlar set up, or buckts, or maybe even just soil not sure yet. But for once they look somewhat healthy, I'm considered about the way the ones leaves look, they are very "swollen." Also, my new growth appears to be coming in with some yellowing? perhaps I don't have enough light? I only have 84 watts on these until my 400w bulb comes in. My PH is good and I'm using advanced nutrients grow, So far I have 15 ml of a and b in 3 gallons which is about 60% strength and I noticed yellowing, I'm afraid to add more and maybe though of just adding revive since it has a lot of trace elements and only nitrogen, no P or K The plants are purple kush, bubba kush white rhino and one purps.
You might be overnuting it, the low level light of the floro only allows the plant to eat about half of what the HID will allow. Try reducing it to more 40-50% strength and see how that goes. Don't buy Revive, you just need to feed it right. Be patient with yourself though, you are doing fine. How's the water temp and the amount of air you have going in the tub?
I just have a really small air stone, not sure the water temps. Should be cooler than whatever it says on the top which at the moment is 78 degrees. A lot of the new growth is lime green kinda yellow, is this normal?
First thing first.Do you have a ph pen and a tds meter.?if you use the lucas formula and change out the res once youv added back the total amount held by your res you can get away without a tds meter.but you must have a ph meter or at the very least some test strips.clones should be at a ppm of 600-700 to start and work up from there.ph should be somwhere between 5.2-6.0. I prefer 5.5-5.9. hydro is quite easy with the proper tools.But without them its a guessing game at best.
No TDS/EC but My PH is 5.5. How are they coming? I'm not sure how to judge, I haven't been too successful in the past.
alright no tds meter.I would highly sugest switching your nutes to the flora series and go with the lucas formula.used properly you can get away without a tds meter. they do look abit burnt.raise your ph to 5.8 and cut the strength of your nutes abit more and give them some time.your going to need to do a good bit of research to do this without a tds meter.but it can be done.
The guys at my hydro store said they only ever check ph. They don't recommend a TDS meter, but they don't say don't get one either. Why should I change my nutrients? Is one really that much better than the other? I've also put a lot of money into the set up, the bucket, the lamps, the hydroton soil nutfrients books time plants and seeds. Can you explain this lucas method?
Most likely they change the reservoir out, which is thumbs down from me. In fact I wish I had more thumbs to give changing the reservoir an even lower approval rating This is coming from a newer grower though, perhaps they have found a program worth that much time, effort, and cost. I seriously doubt it though. The TDS meter is important because it will allow you to see how strong the formula you are giving them is. If too strong add water if too weak add more nutrient. But if you change the reservoir out you don't need one at all, just keep the reservoir topped off. Did you reduce the strength of the solution yet?
I think a problem is that some of my plants are burnt and some are underfed, is this possible? The clones should all be about the same age. I think I need to move some of the less hungrier plants into another unit maybe. I doubt I will be able to fit 3 of these plants in a bubble bucket. I know, I should have built it on my own, but I didn't know how and this is good experience to see how it works, I feel confident than when I have a larger grow I build my own hydro set up. Do you think I can fit 3 plants flowering in one of these? And then i'll have a few in soil and maybe one hydrofarm? Since I have 2 purple kush and 2 bubba kush from the same mother I figure maybe if I do one of each hydro and one soil I'd have a good little controlled experiment going on. What nutrients do you recommend for FF Ocean Forest Soil? Also how many flowering plants can I fit in a space 2'x5'?
You can have as many plants as pots that will fit in the area. You just can't get in the back easily, but with SOG there are only a couple times you need to mess with the plants. Planting them, and pruning them. After that all you have is harvest. Try to fit as many in there as you can and keep them shorter, flower earlier so you don't have to wait on veg. I don't recommend soil if you are already going hydro. I tried it and didn't like it that much, Mr.Postman's thread will teach you how to do it organically though. Soil didn't work out too well for me so I can't really give you an unbiased opinion LOL 3 plants in that tub should be fine as long as they aren't monsters and are spaced far enough apart. One issue is growing lots of strains together hydro- it's not a good idea I've found. Some plants like more food than others.
I have another one of these systems I could fill out half and have 6 total plants in hydro in a relatively small system. yeah here is what i meant about the new growth yellowing, atleast on the purple kush. The first ones are the purple kush, which to me the leaves look distinctively sativa, i like the look a lot actually, and the high. and then the last one is the purps and the one before that is the bubba kush with the fat leaves. Does it look like I'm over feeding?
Yes that looks like nute lockout/burn- they need to be flushed and fed at a lower concentration. Are you sure about the ph as well?
I'd change stores, or at least not bother asking them for advice, because it's pretty obvious they don't know what they're doing. EVERYTHING I've read regarding hydro says both pH and TDS meters are absolutely necessary. Yep. Different strains eat at different rates, so yeah, it's possible. Oh...wait...Mr.G beat me to it lol. It'd check with Ganja Guerrilla in the sick plant forum, but those yellow plants look like you're suffering from potassium deficiency (been there, done that). Check both pH and your nute ratios. Also your TDS. Clones shouldn't be at much more than 500ppm@0.5, at lest for the first few days. Once they start taking off, you can up the nutes.
Ok I'm going to add one gallon of water ph 5.5 to reduce the concentration 25% and then let it sit for a few days? Is that ok? Can anyone explain to me why the new growth is coming in so yellow? It's not that they are against TDS EC they just say they don't use them themselves. I guess a pen would be a good investment in the end though, may save a lot of problems. I'm a little confused on how I'm burning them but have a deficiency. :-( Seems like a few plants are a little overfed and a few are having deficiencies I can't do a lot with one resevoir. Right now I can move half of the plants to another resevoir but I'm not sure which I should put where based on the problems. I thought the yellowing in the center was from N deficiency?
I checked the ph in my res after I added the gallon and it was a bit high so I set it to 5.6. I'm ony using the GH though. I was foolish them because I saw a little brownging leaves on my more indica looking bubba kush and it looked burnt at the tip, but I saw the yellow so I ignored it. I guess the healthiest ones are the purple kush plants, I believe my purps is a little nitrogen overdosed but that should be coming back. Also the bubba seems to be coming in more green, I think it's getting better, I also don't believe I burned them because I think my solution was weaker than the med house. What exactly do I need? A PH pen and a TDS/EC meter? Or is it just one thing?
The solution was not weak at 60% under floros dude- that's the whole problem. Those charts are made for HID lighting the whole time, that's why they say to feed around 2.0 EC- that's a high intensity discharge lighting feed amount. You are using cfls so you need less food. You should be at around 500 PPM on a .5 conversion meter to start under floros. Anything over that to start and you'll risk burn and I'll bet the strength is close to 800. I'd like to point out that this is why I say we should use just as much lighting in veg as bloom, because you can feed them more, they grow faster and more robust... It's just better all around. I'd get the HID over them as soon as possible and turn up the heat. Also another thing I forgot to ask you- the amount of air in the tub. You said you only have one small airstone, so that might be a problem too. How much water is in there with what size airpump? How are the roots looking?
The purps has 2 small roots that poked through the plastic already, none of the other ones came through yet, I didn't want to take them out of their pots. I put about a third strength nutes which are rated at 600pm so i should be around 500ppm but i'm getting a meter soon and my bulb hopefully. the bubba kush greened up super fast, i'm not sure if that's a bad thing? The yellow picture you saw was 2 days old, and now it looks like this. I'm going to leave the bubba kush and the purps alone for a few days and see what happens, I think the nutrients are weak enough, and I don't know about the purple kush, the new growth is scaring me, I hope I didn't kill her.
This is the stealth hydro kit. I already admitted my mistake on purchasing it, but I may as well use what I can out of it. Anyway I have about 3 gallons in each tub so they're about halfway what the recommended amount was. When should I flower if I want them to be under 4 feet tall?
if you want them to be 4 feet tall then switch to flower around 2 feet in veg. thus just assuming how they can easily sretch taller and sometimes double in size. or so I think.
