Browning / curling (up and down) of edges of leaves started 05/21/21 on the orange cookies Since then the OGK and TT have also gotten brown leaves, the Gelato is unbothered Could this be nutes? part of the flush process? I have also read it could be old age? a natural thing? halp

It’s called the senescence, it’s the end of its flowering cycle, it’s natural. 2 weeks flush and harvest 😊

It is potassium deficiency. In flowering you need elevated levels of potassium and phosphorus.
