HELP Brown spots yellow leaves?? pics +rep

1. indoor
2. about 250w of cfl
3.temp 71-75, hum 30-45
4. Fox Farm Nutes, about 1/2 to 3/4 strength
5. I have a pH pen and have been pHing everything to 6.5, havnt checked runoff
6. bagseed veg 1 week ,and I think its about 5 1/2 week flowering I havnt really kept track sorry(this isnt my main plant just kind of an experiment)
7. I water when top inch is dry, and do water, water, feed, water, water, feed

The yellowing started on the older fan leaves then I noticed some brown spots, and its basiclly spreading up the plant fan leaves only, smaller bud leaves are fine so far, what could it be??? I read somewhere it might be some kind of mold, I dont want it to spread to my main plant.

Heres a couple pics of my white widow, same nutes, lights and soil.

Got the same problem bro. Let me know if you find any help, and vice versa

Cool, im just gonna flush the crap out of it today and see if that helps, Ill let you know.

So should I give it some n I have all the fox farm nutes, that's what Ive been using, I added some growbig last friday to the tigerbloob and big bloom I fed it because thats when I first saw the bottom leave start to turn yellow, and its just been getting worse.

ur prob not feeding it enough
it seems kinda early for the plant to start pulling from the leaves

NAW use blood meal half a t spoon. or sum ppl say piss with water does the trick never done that tho

unless he didnt feed it that much during vegg

it looks indica dominate so may be its not too early. if its 5 in a half weeks in flower then he just needs about 2 in a half to 3 weeks to go
