My plants leaves are turning yellow at the bottom and it is working its way up, the very bottom leaves are starting to brown. Is it nitrogen defeciency, can I fix this with miracle grow? also, will the yellowed leaves make it if I add N now? I am really worried

During late flowering the plants suck all the mutes out of fan leaves from bottom up and give them to the buds, unless it's really severe I wouldn't worry too much, if it is severe a photo would help us help you out

Is it flowering or still just vegging? A picture would be really helpful in this case, but at the very least you need to give us much more information.

Well still, how long has it been flowering? yellowing in week one is not normal. Yellowing during week 6 is.

Sorry, I have been feeding it miracle grow, It does have noticeable trichromes and female flowers parts. I have had it on 12/12 for 4 weeks now and not fed in 2 1/2 weeks. It is about 3 feet high. I am using 8 CFL's in a cardboard box grow chamber coated with foil and with a computer fan for ventilation. It was seed grown from a seed I found in some shit that probably came over the mexican border and was likely sitting in a baggie for months. I am using standard vegetable soil.
I will post pics later.

If you've got this far into flowering with only this problem so far, you must be doin' something right. Good luck.

you just answered your own question - 2.5 weeks without feeding it right during the heaviest part of flowering? that's why it's yellowing!
try to get some bloom specific fertilizer and you'll be very happy

Not a Problem, but is this normal? Trichomes on Underside of Fan Leaves? |
