I don't know what the soil is for the first two....but that looks very like abnormal ph and/or fert problems (like maybe too much ferts for seedlings problems) Also...are you overwatering? That will make them sag as well.....and mess with your ph at the same time.. If the third pic is the one in organic soil.....it STILL seems to have a few issues......but not as much as the other two. Be SURE you are not overwatering and have good drainage. If you are sure that's not the issue I'd try to transplant to better soil......sooner rather than later.
Weedhound Reviewed by Weedhound on . Seedlings yellow and droopy Two seedlings have become colored light yellow or light green and the leaves are drooping. These are 2.5 weeks old. One week-old seedling (now as large as the other two), however, is doing fine in the same grow space. The only difference is that it was planted in different soil (indoor/outdoor organic).
