I've been trying to get a handle on the tank's requirements, and have been dosing as needed using pps classic formulas and have been testing fairly regularly. I've added KNO3 & K2SO4 when the nitrates were low (recently). I had also added MgSO4 earlier because somewhere I read that the "veining" was due to a magnesium deficiency. I use CSM+B for iron/trace. Fe runs from 0.1 - 0.25 ppm.
