Hey Jangel, looking good! You do have me curious though about your using nutes with that soil mix you have there.

Maybe try only watering your plants for a bit, watching the upper leaves for signals that they are lacking anything. I think you are goiing to find you don't need any nutes at all.......ever.

You can always top feed the plants, by tossing on a bit more bone meal, prior to watering.

I know I did a simular recipe as yours, and I never needed any nutes at all.
Everything your plant needs is in the soil, you have a healthy (marijuana friendly) recipe there.
Peace
