How much nutes do I add? Can someone explain my next steps?

you want to flush your soil to get a ph of 6, your soil has build up in it, when you flush, let your plants dry out for a few days , i start using the nutrients in a very small amount i use teaspoon measurements so it is way under half of what the feed chart on foxfarms website. the trio works really nice, you can use them throught he whole grow period, i add cal mag every other feed. hope that helps
