3rd Week of Indoor Grow Using Miracle-Gro Moisture Control - Add Nutes?

I am on my 3rd week of vegging 10 plants in Miracle-Gro Moisture Control. Should I not add anything or is it okay to add Miracle-Gro Tomato Plant Food? I want to make this a success but I'm SKEERT! lol

dont use the nutes in it till youve watered that shit for at least 2 months then the nutes will be weak enough to add some...but there is plenty in it allready. if your gonna add anything to it. it should be----bone and blood meal, bat guano, and more perlite. maybe tiger bloom by ff a week into flowering.

oh also. i had some cucumbers in my room and i used mg moisture control in em. i just found thrips so im pretty sure they came in the mg soil....good luck can you post some pics?

I wonder if a guy could add a litle 1\2 strength ferts to the top and water it in for quicker results?
