It's a pH flux. Need to drop your pH more when watering. Bit of Calcium won't hurt her either.

Hi there! Check your pH and make sure you don't have any lockouts or anything. That yellowing starting from the tips looks like a Potassium (K) Deficiency but those curling leaves and darker green says you might have something else too.

HARVEST TIME?
I don't know if I should harvest my plants yet. I've been giving them RO water for the last 1.5 week. One looks her pistils are getting too dark, while the other one has a lot of white pistils but many of her fan leaves and sugar leaves are turning yellow already. Should I cut?

Leaf Discoloration - Hopefully Nothing
I'm looking to rest my concerns that these removed fan leaves from lower/center canopy are not simply just appearing so due to lack of light and prior plant tie damage. Focus on the yellow/brown discoloration, actual physical damage is accounted for. More details in main post.

Yellowing leaves. Zinc/Nitrogen deficiency?
My plant has slight yellowing on the leaves and discoloration and I don't know the exact cause, from research to me it looks like zinc or nitrogen deficiency? I don't think it's too close to my light (last picture). Can anyone help?
