I have some white widow two weeks in under 600 hps, feedin them on bio-bizz my temp is 75-80 and Rh is 30-40 the leafs are startin to curl under and a few yellow spots appeared on a few of the plants i dont understand why.
any suggestions?
i had a few probs with temp and Rh for first week or so but have sorted that out now my temp was 85 and Rh was about 20 could that have caused them some heat stress?
Sorry theres no photo ill try get one on.
im flowering white widow from nirvana seed co right next to a sweet tooth and i have noticed that the white widow's big fan leaves started to turn yellow about 2-3 weeks into flowering. i think its just a genetic trait of the ww because the sweet tooth isnt yellowing at all. the same leaf yellowing during flowering happened with a northern lights cross i harvested.
personally i wouldnt worry about it .once they're yellow enough to come off easily i pluck em off. this also exposes the buds that are being shaded to direct light.
also i've heard that some ww's dont like alot of nutes, but this hasn't been the case with mine
From your description I believe it could be one of two things
Either there is too much nitrogen in your mix (the plant needs much less N during the flowering stage) OR your roots aren't getting enough oxygen
I hope this helps, pics would be very helpful
And I really don't think that the yellowing of a plants leaves that early into flower is a genetic trait, you really only see that normally happening on healthy plants during the last two weeks of flower
here some pics
