sick

LSD - 25 AUTO seed im currently the 3rd week of flowering and the leaves are starting to turn yellow!... I'm using Advanced Nutrients PH Perfect Bloom @ 2ml per litre and the PH is sitting at around 5.8 - 6.1 growing in coco medium temps are at 25c can anyone please help me out with what could...

First time grower here! I'm growing 3 plants in a grow box (hydro setup) under 4 60w CFL's. Still in the vege stage and for the life of me can't figure out why the leaves continue to yellow. I've changed the water every 7 days and do daily ph checks to keep it at 6.0. oh...I'm using Raw's Nutes...

okay. so this is my first grow. i have a used bc northern lights bloombox that i've been repairing the past 6 months and finally got it going. if i could go back in time i would've probably just invested in getting a newer tent but shit happens lol. and im trying to make the best of what i got...
