Ok, the third pic with the two plants on it is a reference. The plant on the right is the same age as the one on the left, only theres a 4" difference. I have taken closeups of the leaves of the plant on the right. You can see discoloration and a little bit of curl-up. I have adjusted pH and nutrients. Is this possibly because of leaf burn? Maybe too much bug spray? Please help!

hey co-d....
it looks like heat stress to me.
do you know what your relative humidity is?
what was your ph, and what did ya change it to?
im going to move this over to the nursery, where ya might get some more help.

yeah so sorry about the double thread, i guess it takes a few minutes to update.
so the relative humidity is around 50-60 at all times, temp at leaves about 80, ph should be good around 5.8-6. i have 2 14node of the same strain that have no problems.

well, rh looks good, the temps are a little bit hight, but nothing too terrible (i prefer around 74f)....
the ph sounds a little high at 6.
i usually start at 5.5, and let it drift to 5.9 before i drop it again.
if you have same strain from seed, you will probably find some differences between individual plants. some of these differences could be in the area of feeding requirements, so what might be good for some, might not be good for all (if working with a shared res).
to err on the side of caution, bring the ppm down for a bit, and drop the ph to about 5.7.
give it a few days ad see where it goes.

I've changed the watering schedule and lowered the ph. Now, I am getting strong green growth at the top of the plant and a lot of the heat burned leaves have gotten very brown so I have removed them.
I will keep you posted.

i see alot of new growth so thats agood thing:D ansd ya it wouldnt hurt to get another fan in there good luck man peace
The smaller one is not getting as full and bushy as the other one (the one I pointed at). Is it possible that the stalk has a disease of some sort and is rotting? The irrigation might have been pumping water directly onto the small one for a while (when I first transferred the plants to large pots). I don't know. Anyway, heres some pics, let me know what you guys think please :confused:
