So this will be my first Indoor grow I got 400w Hilide with Reflector i got the proper ventilation, using miracle grow, nice soil. Im planting 5 White Widow Plants, but will they grow over my light?
Miracle grow soil has a lot of slow release ferts that may damage young plants. I'd mix it w/ some other soil. You don't need a bottle of N a bottle of P etc... Miracle Gro water soluble (24-8-16) works just fine if you're going on the cheap. Mix 1 TSP per gallon of water, feed young plants a 1/4 cup (1 gallon pot), 5 gallon plants can take a 1/2 cup. Do this every other watering, if they show stress, flush w/ plain water and dial the amount back. When they are larger 2 TSP / gallon is good. Last 2 weeks flush w/ plain water. If you can afford it, i'd go w/ Fox Farm nutes, organics, and less likely to burn your plant.
MG has a element missing for the nutes. Magnessium. You need it to keep the leaves from getting all spotty and brown. Thats also why mg sucks big
