Looking good @jimmybud. Just my two cents worth, unless you started with poor to moderate soil, shouldn’t need to be fed for the first three weeks (or more).
As an example, my plants are 29 days old and I have yet to feed them, just pH adjusted water. They are healthy and growing fast.

I will be transplanting this afternoon which means more fresh soil. No nutes for at least a couple more weeks, probably longer.
