Seedling stage needs no nutes...unless it's a very low dose of B-1 for root structure enhancment.Organic nutes ,I heard the same thing but why would you want to overdose your plants .Just give them about 1/2-3/4 of the recommended dose.Ween them onto the nutes...start seedling stage 1/4 dose and work your way up to 3/4 dose and I wouldn't exied that.
