If you really wanted to double up on anything, it would be the K2SO4. The CSM+B and KH2PO4 will be used the slowest.
FWIF, here's my regimen for my 46g...
Macro days: 1/4 tsp KNO3, 1/3 tsp K2SO4, 1.0 ppm KH2PO4 (via premixed solution), 1/4 MgSO4 (Epson's salt...a recent addition!)
Micro days: 10 ml of CSM+B (1 tsp per 250 ml)
Start dosing macros on waterchange day. Dose each 3x, and skip a day before the next W/C.
