Z4Z0Zanswered grow question 2 years ago The 45W air pump should be way enough for this system;
The plant looks like it needs some peace and recovery time;
Try to keep it around 25°C with 60% RH;
You can lower your light distance to 90/100cm if you keep it at 40% for now;
The little clone looks like overwatered or a bit burnt (is the air pump already working ? maybe you can pub half nutrients for now ?).
