Slimey, did you start the seeds in those pots? or are they transplants. As Buds said, their big pots for those seedlings. Makes it harder to manage the little plant. It looks dry from the pics, but you only need to water an area the size of a tennis ball or less. That makes it hard to check your pH in-out which is very important!(im learning that now). I wouldnt be giving it any nutes yet either..just pH'd water. I'v never started directly in a hydro mix, had really good success so far with soil/hydro mixed together. good luck, keep us posted
