I see a problem.
You are drenching the soil with seed, before there are roots to uptake the water, and it sits there and stagnates, and keeps oxygen from getting to the roots, as well as allowing chemical reactions among the components of the fertilizer in the soil, and the soil itself.
Water new seedlings LIGHTLY, to JUST MOISTEN the soil around where the actual seed and its root are.
