You do some very nice work with your grow technique, impressive. 
I have stuck with true soil, attempting to do organic as close as posssible. Just towards the end when flowers are getting close is when the soil tends to lose something they need. I strictly use Gaia Green a certified organic fertilizer when needed, but mainly try and feed teas of various mixes. I am on my next attempt going to try coco and make it a living soiless grow. One of my favorite products is Mychorizal and also Bio Live from Down to Earth and Bio Char pre-inoculated (has microbes pre-charged). I do get the fungal growth on the top of my soil which I believe is from the Bio Live. Anyway thanks for your post, glad I looked into it. Keep those girls going!
