my 2 week old white widow plant started getting brown spots on some of the bigger leaves on top and the 2 old big ones at the bottom are turning yellowish. i've been watering every 3 days with 6.5 ph but i noticed this after i moved it into a bigger box...so maybe it has something to do with that? my room size is 6'(h)x5'(w)x27"(d) all white walls with 2 fans blowing around the plants and about 4 daylight CFLs, 4 daylight mini CFLs and some soft whites are scattered around. the box isnt completely sealed yet but it's all covered. I'm using FFOF soil which i gotta say i like it. other than the white widow i have 9 LR2's that are a week old in the same box with the same lighting described above.today i repotted all the plants into bigger pots and i noticed the white widow roots were wrapping around the bottom of the pot so im guessing it already needed to be changed which i had planned last week but didnt get around to it. as for the nutes i have FF Grow big, Big Bloom & Tiger Bloom but havent started any nutes yet. im not sure what the temperatures of the room are cuz my thermohygrometer is out of battery but humidity is at around 50 via cheap humidity gauge from my cigar humidor. well any help would be appreciated...thanx!
