When your FoxFarm nutes arrive...start it out 1/4 strength for a couple feedings, than 1/2 strength for a couple more.

Prior to that, flush your plants and get that Miracle Grow business out of the soil. Mixing organics (FoxFarm) with chemicalized ferts tends to produce a less than stellar growing medium. Instead of a compliment, you'd end up with the two counteracting one another.

And if you're not shooting for stellar...well...why bother eh.
