Hi! Without essential data like pH and ppm of inflow/runoff itโs hard to guess. Maybe thatโs just odd first leaves. The rest are looking great. Possibly pH issue, light overwatering or a bit hot soil (too high ppm). Not fungi or pests. I think thereโs no issue here. She needs transplanting in few days. Why do you use 12/12 light schedule from seed for auto? Just curious ๐ง
