Wow, did you throw it into the sun? More than 1 problem their. there is no saving the flowering ones. They will be so fucking stressed they will herm or just die, once a leaf turns yellow it cannot repair itself and can no longer take up light. the chlorophyll in the leaves (green color) are what take up the light. once they die, well, their dead. I think you should do some more reading on how to grow and proper nutrient usage, 2 months of just water isnt that good either if your soil doesnt have nutes in it.
Yellowing leaves can be recovered within reason.
Not every heavily stressed plant will hermie for certain.
ive never, ever, ever, ever, seen a yellowing plant recover. ever. eveeerr. Lol unless you pump it with ton of nitrogen to force it green? lol idk ive never seen a plant recover from yellowing in flower.
Hmm. I've had yellowing leaves from lack of nitrogen and calmag bounce back completely after feeding. I guess it depends on why the leaf is yellowing to begin with?
Are you talking about growing new green leaves? or the leaves fading getting their green back? ive had lack of N before and never once seen the yellow ones come back to green, just new green leaves growing.
