Hi
@ItalyGrow looking at your plant it seems to me the effect of 2 things: Defoliation stress and the substrate is soaked. Automatic plants hate stress, the secret of defoliation is to do it slowly and gradually, you do 1 defoliation and let it rest for 5 days and do a little more so the plant does not stress. this together with the soaked substrate leaves the plant like this. apply less water in each irrigation and let the substrate almost dry out between each irrigation. good luck mate 👍
