I start them in solo cups with 75/25 FFOF and perlite in a computer case "incubator", then transplant at day 14 into a mix that is 90/10 plus some dolomite lime.....NO NUTES for 28 days...LEAVE IT ALONE....everyone wants to jack with a grow process that is very short to begin with.....you cant unburn your plants and VERY LITTLE time for recovery..then 1/2 strength plus a few other goodies after that..
