Something is de-capitating some of the seedlings, some more than others, basil being a favorite. The seedling up 1/2 to 1", still 1st leaves. This in a tray of 10 peat pellets, outside, light shade, out of rain. I don't know if it flies or crawls, leaves gone, the stem remaining straight up. I've moved to a different shelf, problem follows, then back to inside. Once true leaves grow, seems to be OK. Any ideas?
