the fan leaves on the main stem are green and doing well but the leaves on the side stems are yellowing and falling off(when i touch them they snap off) growing in dirt pH around 6.5-7( my ph meter broke) 5 weeks flowering(10-12 week strain) ASH - MNS seedbank temps 25-27 C and 22-25 at night( lights off) i feed with bloom nutes but because i thought it was N def i gave a foliar feed of N and mixed some veg nutes in with bloom but the leaves continue to fall. In a 1 gallon pot, i dont think its rootbound but im not quite sure, growth is quite stunted aswell..

Gallon pots are dinky. 3 is better. Some strains eat nitrogen from leaves during bloom and is normal. Some add a bit to nitrogen to nutes during bloom.

good luck bro:weed:

In the first pic it looks like the veins are remaining green while the margins are yellowing. I would say they need some additional Magnesium....

not enough light. they can't photosynthesize so they break down whats left in them for the rest of the plant. Its common with small CFL grows like yours.

they are all getting plenty of light some of the fan leaves in the bottom which are getting even less light and are older are perfectly green. so im quite confused.

bumping your thread after 5 hours will just keep people from answering your message as you look annoying.
the CFL penetration is very low. while you might see "plenty of light" the leaves don't see enough of it.

im sorry but my plant continues to die and i really dont want that to happen. leaves near the lights are dying too so i dont think thats the issue, ive fed with all macro nutes in low dosage, ph 6,5-7 in soil i dont overwater for sure. i dont know what could be wrong. ive checked everything.

have you pulled a plant out of the pot ( when soil is dry) and checked the roots? Are they cramped and root bound, what color are they. A nice white color or more tan?

could it be rootbound? if it is and i cant move it to a bigger pot what can i do?

i have two 6" fans intake and exhaust with 2 PC fans forair circulation and its in a TV, in the day all fans are off could this cause problems too?
