Yellow leaves (a lot of them)The plant is showing a lot of yellow leaves. I think it's a little bit early to speak about a natural loss by flowering, or not?
There are also a lot of yellowish leaves (more yellow than green even): what is the problem?
the red leaves are normal to this strain I think? Thanks!Week 10

Late flower issues- chop early?Week 8 of flower (haven't been best at keeping up with diary). Poor girl is deteriorating rapidly but I don't know why. Too late to fix, but too early for ideal harvest. Should I just let her ride or chop early and try to salvage what I can?2y ago

Yellow new foliageFrom my research it could be phosphorus toxicity, iron deficiency or sulfur deficiency.
Or it could be over watering.
Or it could be poor drainage.
Or it could be light deficiency (I have a 42watt Tled with some led strips until Mars 600 arrives)Leaves. Color - Yellow
