So what's you feed schedule daily, weekly, don't say every watering that means nothingIt's been working quite well for me. Not sure what your problem is.
First of all, I grow in hydro. 3 feedings a day and I have reached the point where my plants can handle the full dose(worked my way up from 1/4 strength. If you're growing in soil, start at 1/4 and see how they respond, then work your way up. Use the nutrients every other watering. Water when the top inch or two of soil dries and NOT before. The soil needs to dry out a little so the roots can expand and search for water.
No mystery, just a rule of thumb when I start giving nutes to a plant, particularly if I've never used the brand before. Going full-strength can mean burning your plants the first time out. Good thing about Foxfarm is that it's organic and won't burn your plants as much as chemical ferts. So stick to the schedule, only start off at 1/4 strength until your certain your plants can handle the full dose. Still don't get it?
