Welcome to MP Whitman. You should have no problem finding help over here with your grow. There are alot of smart people here with some killer indoor grows. Hope to see ya around the forum. I myself use Fox Farm products.
Most dont start nutes till the plant has been in veg(Growing Stage) for at least 2 - 3 weeks. One thing to do no matter what ferts you choose is not to use a full dose the first time use 1/4 strength to 1/2 strength at most. Some plants love nutes while others are sensitive its all in the genetics.
