My autoflower has been strong all the way through growing cycle but recently leaves started curling down and and leaves are starting to get blotches of purple. Any recommendations what the issue is and how to fix it?
its the cold stalling the sap in the leaves, its what makes cabbage-apples etc red! its called anthocycline or sum such good luck
Looking like a miracle grow plant. This is about as good as they get using there nutrients . Poster what are you feeding ?
