@Cave Dirt Cody - That is a honkin unbelievable setup! Killing it as usual in there. If you do switch: The pH comes out a little low on the Jacks in plain RO water. A few ml's of silica brings it up nicely and isn't a bad addition on its own. I've found the EC and pH to be very stable doing that. I think at full strength it mixes to 5.5 or so. Obviously test and tune but I found 1ml/gal of the silica product I use brings it to right between 5.8-6.1 most days.
Day 50.

Outlier Z on the left. Purple pope in the middle and Queens Banner on the right.
All three are on Jacks 321 @ 750 to 800 ppm. 3.6 grams of A Part, 2.4 grams of B part and 6.5 to 7 grams of Epsom salt. A little more epsom then the 6 to keep it at a 321 ratio, but seems to be needed with the big light.
