Actually if you are going to use MG the best ones they make for your gals is Miracle gro tomato for vegatative growth and their bloom boost for flower. Only after 3 weeks at least. But read the tab inside the box! Most people make the mistake of not reading the inside of the box because it says 1 teaspoon per gallon for indoor or potted plants! On the outside of the box it says 1 tablespoon, do not do that lol. This is a labeling problem that has given Mg a bad name, and it is something that just baffles me why they don't put all the instructions on the back. So remember 1 teaspoon per gallon every 1-2 weeks.
