5th week of what? flowering?

nitrogen deficiency generally tends to work its way up from the bottom. So my initial guess would be N def.

still battling those mites huh? you need to get those little bastards under control man :-p
Gundari Reviewed by Gundari on . sorry just dont know hey im not sure if anyone has had this specific problem but the bottom fans lfs are turning yellow and pretty much dead. everything above that first level of fans looks real healthy and green. i did have some spidey mites on those leaves at arnd 3 wks and i just ran my finger down the bottom to remove them and goin on the 5th wk now. could that be the reason for dying leafs any suggestions for the problem? or was it just bc i ran my finger down the leaf, but i dont feel that was harmful.
