Sick Sativa

Hi, ill post some low quality pics as soon as the battery is charged but here is my problem as best i can describe.

I have an unknown sativa strain growing under cfls. Not the cleanest or most expensive set up but i dont have much money so it's all I've got. Shes about 6 weeks into flower, but around week 4-5 began developing problems. She has Yellowing veins which spread out to cover the whole leaf before the leaf inevitably dies. Also even the leaves which appear healthy are curling downward and have yellowed tips, although no yellow tip is more than one milimetre long, and a few are developing small spots on the leaf itself. Each cola just feels flimsy, some even bending over, although that could be due to weight, it has a thin main trunk. I really dont know where else to turn, so Thanks for any help you guys can give :)

sativas aren't the best choice for fluorescents. they have a tendency to be stretchy and rangy. tip burn usually means over ferting. what kind of nutes you using? ph? pics would really help.

Try copying and pasting the troubleshooting form here, and fill it out as best you can. Pictures would help.
Could be rootbound, could be calcium defeciency, might be lack of usable light. The troubleshooting form will help nail it down. :thumbsup:
