looking great rob.. really nice job on the scrog dude!

hows the smell so far, inside and out?

[RobsGreen]

Hey, thanks for the info guys. See I always get those CFL's mixed up, thats why I have so many of the wrong ones. I have lots of 2700k I need a 6500k, the 2700k is in there now. I was only going to use a 43w for mom, I don't need her to grow very fast. I thought the light leaks would be ok, there not that bad but I know they're there because light comes out.

I definitely like the way this scrog is going, I can't express how happy I am when I see it nice and full. I have big hopes for harvest on this one. IMgreen you should definitely get a screen for your setup you should get a nice yield using it although its quite a bit of work though, I've spent many hours moving and cutting.

The smell isn't a problem at all at this point, absolutely nothing outside the box and not a lot inside although its smelling better everyday. There was more smell before I removed all the leaves, that really helped. Well time to change all that and smell the place up.

Well I still have some leaf issues, not super concerned because the buds are still growing rapidly and the leaves have looked like this for a long time but I would really like to know what it is. They still have the same spots when I had PH issues but now my PH is rock solid at 5.6. I had my nutes set to 1100 @ .5 and as the plants have drank the water the PPM has gone up to 1410 but the PH hasn't moved a point so that makes me think its ok that high. I have no sign of nute burn that I can see but I still have what looks like deficiencies. Here's some pics of the leaves, any help would be appreciated.



This one has some leaf missing, I have others like that too but not lots.


Here's the spots from the bottom, quite a few leaves with spots on #1 but not so many on #2 the way its always been.


Here's some spots from #2, a lot less.


And here's some bud shots, camera finally gets them under the HPS.

Looks like late stage Cal deficiency.
Try 1/2 teaspoon of pulverized dolomite lime or Garden lime per gal of water and adjust Ph as usual. Or foliar feed when not in budding with 1 tsp per qt of water, adjust ph as needed.

well said.

[IMgreen]

I agree w/ don piano

got the EXACT same spots on some of my leaves too at almost end of flower

once something like that shows up you can stop it from spreading but the leaves wont heal

I opted not to worry about it

[screwdababylon!]

yeah man
i wouldnt worry so much ether
all the elements are there with the 1100ppm
just a little help like don said would do

do u think its anyhow connected with the trimming u have done
any ideas?

great progress tho
im fucking jelous )))
its ok as long as i admit it) right?
good luck bro

[gonejah17]

Man I gotta read thru this thread one of these days man, I love the cab so much!!!!


Yeah man definitely not bugs homie. That rusty shit is cal for sure.

Ur toppping ur res off w RO before checking ppm levels right?? When u say it went from 1100 to 1400 did u top it off before u read the 1400??

Im in man -- gotcha tagged now!!!

[RobsGreen]

Right on, glad you all agree. I know the bad leaves can't be fixed but this is all new growth and they still have it, it almost looks like its gotten a bit worse. Don what does "late stage" mean? I don't really want to add any other additives, I think you mentioned your not a hydro guy Don so does the same measurements still apply? I have a lot of water so that would be a lot of lime. Can that be found at a garden center?

screwdababylon! lol, I really don't think it has anything to do with the leaf trimming, IMO that was the best thing I did this grow. Its really seemed to have help growth up top, the buds are getting bigger every day, I'm pretty sure they're quite a bit bigger at this point then my last grow. I will definitely be trimming like this next grow too. Since I messed up at the beginning they have always had bad leaves but I wasn't too concerned because everything seemed great lately but I should still try and get it corrected, I have a long way to go.

gonejah17 glad to see your here, you did have me a bit worried, I was thinking is it terminal and their about to drop. lol I usually check the levels everyday when I first open the cab then I add any RO water if needed, recheck a few hours later and record those numbers. When I add water it's usually not pure, I usually add nutes to bring it to the same level or higher as the res so they always stay up there. Doing it that way I also don't need any PH up or down, usually it comes to 5.6 on its own. My water temp is at 71f and usually is around there sometimes 2 degrees more but thats it. Once my camera gets back here I'll post a pic of my numbers.

[Don Piano]

Yeah, it definately had nothing to do with the trimming. Any Cal additive will work. Lime can be found at the garden center (get pulvurized dolemitic lime if you do, granulated will mean pulverizing yourself.
I am not a hydro guy, but the foliar feeding keep the same as posted before, for adding to the res of a hydro setup, go with half of the above post (so 1/4 tsp lime /gal) I just talked to a hydro buddy about it , actually forwarded him your pic and discussed it with him, and he says half the strength that you would use in soil, so it's from the horses mouth ( a hydro guy).
Again, lime does not have to be used, molasses is rich in calcium, and if you are not using it already, you can benefit from it just like us soil guys do. only use during budding. My hydro buddy says just use a weak dose to start, nothing crazy (1tsp/gal)



Late stage is meaning that the deficiency has been there for a while, usually early stage will be some some yellowish/rusty tipping near the ends of the leaflet veins. Like so..

Im kinda new to hydro but IMO u should top off the res before u take ur readings. That should give u a more accurate idea of whats goin on. But I could be off base and Im reallys stoned right now. I forget ur nute regeiment, but I would say ur either givin them too much or not enough, I really gotta look back over the thread to get more info srry. But if I were to guess and goin by the fact that ur not getting any real burn Id say probably too little.

[RobsGreen]

Hey Don thanks for taking the time to do that, I really appreciated it. I certainly wasn't doubting you, I have a good feeling you always know what your talking about. Just thought I would mention it. I'll probably see if I can pick some up tomorrow and see what it does, is there any chance it can have a negative effect?

Your certainly right about late stage it has been there for quite a while but the last few days seems worse even though the PPM is going up. Today it was at 1430 @ .5 and the PH @ 5.6

gonejah17 I do check my reading after I top off, I check them before too though just to compare. I wait about 3 hours to check them after I add. I was also wondering if maybe I'm giving them too much nutes as its been going up and the spots seem worse but like you say theres no burning to show for.

[Don Piano]

I appreciate the kind words.
Not a problem Rob, anything for a fellow operative.

I can not see anything different , other than ph, and tds/ppm.
You are in budding correct? If not, foliar feed. If so, what are your nutes (I have a feeling Lucas formula), forgive me for being lazy tonight.

Molybdenum can get locked out by calcium def, and if your plants cant get that, you end up with smaller than usual buds and slightly slower growth. Cal def in the late stage usually affects the newer growth first, so you'll know when it's fixed.
