I don't have good ventilation system, I can't do that. Only think I can do is move those two 105W (2700K) higher and turn of those two 45W(5500K), but that would increase distance from the bulbs to plant to 30cm (about 12 inches). Would that work? To decrease the temperature to maybe 77. Would that be optimal environment for healthy grow?Looks like it's on the warm side in your closet. During flower keeping temps below 70 will increase bud size
Looks like the start of a Magnesium deficiency. Get some epsom salt, mix 1 tablspoon per gallon and feed the next watering. Some people use Cal / Mag but epsom is cheap, readily available, and does the job well. Plus, you don't want to give your plants extra Calcium if they don't need it.This is from a bag seed and I'm not afraid about that one cause it's almost finished, only 4 days left and it's going down:

But this one have about 3-4weeks left and I don't know what to do with it.

If you know what is it, pls let me know...?
Ok I found this product which is apparently made for this problem. It is called Sequestered Iron Plant Tonic, it contains iron with manganese and magnesium, that should be it, right? That should help? Thank you for your help and opinion.Looks like the start of a Magnesium deficiency. Get some epsom salt, mix 1 tablspoon per gallon and feed the next watering.
