Notes:
Last week's plants grew well, I'm going to continue the current water change formulation, with some minor tweaks. I reduced the Amquel a bit to see what change would happen, if any, and I upped the K a little bit to try to optimize initial growth. What I usually see is little growth in the first couple days, until I do the next dosing of nitrates/phosphates, and there are initially some brown patches in the stargrass. It might be because there is not enough K from the water change, which gets added when dosing the KNO3 and KH2PO4.

50% water change:
15 mL Amquel+
30 mL Excel
2 tsp CaCl2
1 heaping tsp MgSO4
2.5 tsp baking soda
6 ppm K (not including K from KNO3 and KH2PO4, which adds roughly 10 more ppm)
2.4 ppm PO4
15 ppm NO3 (added hours later)
