I am growing white widow in soil. Some of them are growing fine (gaining size) but the lower leaves seem to be going yellow with brown spots. Others are not growing at all and the lower leaves have the same defect. Any ideas?
I thought magnesium deficiency, but they are only seedlings, 2 weeks old.
Thank you in advance
