It is just about impossible to troubleshoot as I have four plants in identical soil, from the same seeds, same size pots, same watering schedule, same lights and environment, etc.

Two are bushy and nice and green and two are much smaller with yellowing, but not sagging or curling, leaves. The smaller ones are propped up to almost the same height as the larger ones.

They are 3.5 weeks old and received one weak fert treatment in water.

Any thoughts?
