Yellowing Seedlings

WendyhouseGrowerstarted grow question 3 years ago

My seedlings seem to struggle. My temps are quite cold at 20°C. I'm using a 400w MH light, they are 2 weeks old, I know the cold will make them grow slow, but they seem to have yellowing leaves. The light is 80cm above the tops

The only reason I can think of this early would be soil pH being way off or the soil being too compacted/rich in nutrients. Overwatering could cause this too I suppose.
