i have a question about watering my seedlings. they are a week old and yesterday was their first shot of 1/2 strength nutes. i have a fan in my room to blow the air around, but it keeps on drying out my pots. i let them get compleatly dried out before i water again. the question is should i feed them nutes everytime i water (which has been about every day to day and a half) or should i use fresh water some of the times?
