Yellow leaves on my girl !

Hey whats up guys. This is my first grow. I have some leaves turning yellow with some brown spots. Looks like its starting to shrivel up a little too. The one I'm having a problem Bubbleious. The Bubbleious and AK47 are a little over 3 weeks old. The AK47 is doing pretty good. Also got a Candy Kush in the back about 2 weeks old. The soil is Fox Farm ocean forrest. I started Fox Farm Grow Big nute about a week ago. The AK47 took off and the Bubbleious .... not so much. I got a full spectrum 60 watt CFL, and a 125 watt CFL with a reflector. They're about 10" away. The temps are about 72-85 degrees, and 30-60% humidity. I have a humidifier on the way, and also a new exhaust fan on the way to help with the heat problem in the box. The temps outside in New York are about 60 at night to 85 during the day. My apartment gets a little warm when I shut my growbox. The soil is kinda damp when I stick my fingers in there. Might be overwatering it a little too much. Think thats about all the info I can give you. Oh yeah, the PH level is 6.8 on the bub and 7.0 for the AK47. Usually give them a little nute every other day. ( someone on youtube swears by it). Anyway, If you have any ideas, please let me know... Thanks in advance... Peace...

look into super cropping on your larger one, if you decide to use it come back here and post before you go for it. you might think about adding some calmag + , also what kind of water are you using?

i also think your temps should be ok mine are the same and mine does fine.

I was using distilled when they were seedlings, but the last few weeks, just tap water. I was going to try calmag.

during the summer, it was getting up to the mid 90's in there, but then I kept the AC on all day and it helped bring it down.

Pic1 - your feeding to much (N). your leaves "rrrrr" getting to green.
Pic2- Looks like a a (P) deficiency.
IMO-I'd use the Cal/Mag every month as a preventative measure all through the plants life.


Good Luck with You Grow
