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!

Picture please.
However, going by what you're saying, sounds like a pH problem or overwatering. Watering every three days, in high humidity, will cause damage. The pH problem could be coming from the soil now being too acidic (I try using pH neutral water all the way so I can gauge what's going on when I pH test the soil.)

im thinkin nitrogen man ...but im honestly not the most reliable source i got about 12 white widows n they do the same crap but when i add some peters 20 20 20 nitrogen is the main ingrediant...i think ...youll get used to your strain over time

20 20 20 means even balance of nitrogen, potassium, and phosphorous, 20% each.
i was thinking it mightve been from getting water on the leave but im not sure. i'll see if i can get pictures up also. right now i dont have any fancy equipment which is why i cant keep good track of it but im slowly working on it. all the LR2's look fine its just the white widow that looks weird. i added a few drops of grow big and big bloom to my white widow last night so lets see what happens. when i repotted the soil was really dry so i know for sure it needed to be watered.
