@dvr147, also after looking at your photos I see that when you spray you spray the plant as well.. I personally do not do that I spray the dirt around it and try not to get too much water on the seedling one of the photos there's a big water droplet that water droplet can act like a magnifying glass with the light and burn that leaf and at this stage would ultimately probably kill that plant so after you spray take a paper towel and with the corner just tap on the water droplets without disrupting your seedling
