5-1-1 under LED
Just a note to say that the 5-1-1 mix is working very well under LED lighting. I have lettuces and peppers growing very well. I am also using 6500K T5's to supplement the light of a 120W LED. I have peppers growing fruit as we speak.
It seems the advantage of Al Tapla's 5-1-1 mix seems especially relevant under LED. Reason being is that LED is very cool, and water retention seems to be more of an issue then under warmer lights such as HID (especially in a basement as I have going). I no longer have issues with fungi or overwatering/overfertilization that I had with commercial potting soil. It's difficult to over do either with this mix. Anyone attempting to grow under LED should consider this mix. I hope to try the gritty mix as well soon, although since my main focus is vegetables, I will most likely continue to use the 5-1-1 mix.
