Auto Sea O' Green: 4 Strain Mean Machine

The sailing got rough this week. One of my Criticals died -- just failed. The buds just fell over lifeless. Two other plants - 1 NL and 1 Critical are showing problems. All of this happened shortly after I added more living soil as a topping along with limestone to balance the PH. That could be a coincidence. I remain worried the density and small bag size is the problem. My sea of green research suggested different options, I perhaps I was greedy. That said, the other NL and Critical, and all of the SC and WC, are looking good. So who knows.
