lil problem i think

[rubbfuzz]

hey people whats goin on? My sativa is in its seventh week of flower. Most of the leaves on her are all yellowed and dryin up. She was all green up to about a week ago. I havent changed my routine as far as watering and lighting. Also the clone that i took from her is also in flowering and about 2 weeks behind, and is still green. problem is im just staring to see trichs on my first gal now. whats up with my girl? is it normal for the leaves to start to turn before the plant has trichs? The trichs it does have seem to only be on the small leaves by the buds, but there arent many at all.
any advice would be awesome!! Also ive heard that some strains dont get visable trichs at all. If thats the case how will i know when shes done and ready to be harvested?

Are you feeding it anything ? My last two plants were not fed enough with any consistency. They finished very yellow, the second set of photos is last nights ugly duckling.

if they are yellowing they might need nitrogen....and if they are drying up whats the humidity? have you watered enough? theres a few things that you could have going on....rootbound, PH or nutrient dif.....

a pic and more info on the grow at least would help. whats you total grow setup including medium and nute schedule?
