thats the thing its white widow and i got Blackberry stativas i believe just no new growth realy if there is its real real slow but everythings greeen and not yellow at all
a lot of strains do that... my last grow had stems of purp, no purp buds.. do a search on it big ass topic and no definitive answer as to why some plants do that. my purp stems faded away a lot after i started giving nutes and teas that's my experience..
White widow on the left Blackberry on the right. at first i though it was something to due with nuets so im using water right now and will until they are a bit bigger then go back.
