Hey Growmie, I think it’s being over watered. This refers not necessarily to the amount given, but the frequency (how often). If the roots are being suffocated, this growth will occur, wrinkled, and crinkled leaves, growth clumped together and if you look closely at the leaves, they may also have a bumpy texture to them. I would say let the medium dry out quite a bit more before you water next, and then again and you’ll see them bounce back. 👊🇨🇦❤️
