Sweet ZZ

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
