I have a few seedlings going, and they have been doing wel, but in the last few days the bottom leavesare going a bit yellow and drooping, is this an overwatering issue?also wondering, will potting soil go "stale"? I put some in a few buckets, forgetting that I won't be ready to transplant for a few weeks, so the soil wil be sitting there with nothing to do for a while??P.S.- I'm doing a 24/0 cycle
