Just had a nightmare with my plant drooping. I’d just done a res change, checked it 30 min later and all the leaves were dropping. Immediately checked the ph and jut was too high at 6.7. It was 5.8 when I set it up ( think I need a new pen) I adjusted the ph and it bounced back fairly quick. So for this issue I’d say check your ph and that your water temp isn’t too low.
