Because I didn't have the best materials ordered or on hand, I made several substitutions with salt which is all immediately available. I was impatient and just wanted to get something on the burner with the EWC for the month. I think it might be a little too rich in ammonium, which would be most sad as I just learned that hard lesson in hydro, lol.
In the High Brix thread I believe, I read that the garden lime has to much mag to cal in it and that is counter productive to the uptake of calcium. Doc's blend is about 10:1 Ca:Mg, but the garden lime used in the
Faux Mix recipe has a ratio of 2:1. So to ensure calcium is readily available, the soil amendment should not have too much antagonism programmed into the recipe. Also in that thread was the suggestion to amend with calcium carbonate to emphasize on the calcium only while still buffering the PH, so I did that yesterday with the start of the 2nd batch of mix.
