Ok heres the deal, im pretty f'ing high and paranoid about my babies.
I have a 4x4x6.5 grow hut with a 600hps light. its ventalated by a 6in inline exhaust fan. temp varies from 69-77 throughout a 24 hr period. The humidity isnt where it should be, its stays around 35% I bought 6 clones from the local club 1 week

3 days ago. 2 purple haze, 3 gods gift, 1 cheese. They were transplanted into 1 gal pot about 5 days ago. they are in fox farm soil. about 3 days after they got home i had to water and used a light formula of fox farm big bloom to help out with the roots, and just last night i used a normal formula of fox farm grow big.
Only one plant sarted to get these black spots and now its on 4 of the six clones. The first 4 picture's symptoms look the exact same on 4 of the plants. Now the last 2 pictures are the cheese plant and this plant doesnt have any of these black spots, instead it has retarded looking newer leaves.... i mean the growth is weird as hell!!
PLZZZZ help me I realy want some expert advice
