Question about MG

I am on my 3rd grow very low cost cfl with bag seed(I wanted to practice before I spent money on expensive lighting and seeds), I am using Miracle Grow Moisture Control and am having some success, My question is how long should I wait before giving them nutes because I have burnt a couple?

Not sure, but I think MG has time released fert's, meaning that if you add your own on top, you might burn em...as you did. My first advise is always dont use MG, its the Mcdonalds of fertilizers, but if you're stuck with it, just don't nute until the flowering stage.

I use MG moisture control and I dont give any nutes til about week 2 of flower then I use a very low dose of bllom type ferts and ease them in at 1/4 then 1/2 strength.I then add something like sugar daddy, sweet or garvity from humbodlt county..Mollasses works good also..just use good old ph balanced water all the way through no nutes need..Sincerely FilthyFletch
