gREEn7o0answered grow question 2 years ago At seedling stage just give water. Seed has what it needs to start life.
I usually wait until plant is 6ish inches before giving nutes at all, just ph'd well water until then, (if using RO or dechlorinated tap water may want to add a little cal mag) and when I do start on nutrients I give 1/4 strength.
Then 1/2 strength for early veg.
Full strength from mid to late veg.
I'm using GH maxi series
