Yeah, I have 3/4 bottle left from before I put in the MGOCPM. I'm not very well-versed in how things work, and I'm thinking that the substrate is helping plants with heavy root activity and maybe the previous dose of Flourish Comprehensive every week would do some good for leaf-active plants. Instead of waiting until it dries out
Also, the way I understand it, eventually the plants will exhaust the substrate of ferts and I will have to start dosing (my substrate is now, in a 10g tank, 1" of MGOCPM and 1" of Petco black sand). I have some KSO3 or some similar K compound. At that point I will certainly do dry. But thanks for the pointers.
