DrJynx86answered grow question 4 years ago Those are the kind of leaves you usually see when plants are revegging. They might be clones from a flowering mother and that would explain it, or maybe a light leak.
But they're nowhere close to be looking bad, on the contrary, very healthy, they just need more weeks to grow and fatten up, keep patience!
Just in case, make sure you're not overfeeding Nitrogen, as the kind of curling down might be that, but in any case, keep up with the great care!
Happy smokes!
