They all call it "new father" syndrome, here on the forum. We all do it.
You will get over it after your 100th grow or so..... as I understand.
LOL This! I used to stress over these plants a lot. But after a while, I just got to the point where I just let them grow and respond to problems if and when they pop up. Usually just a quick peak in the tent once a day to make sure they are still ok. Plants do a whole lot of nothing much when they grow from day to day. And especially seedlings because most of the growth that is happening at the roots in the first week.
