@John q
Weekly Dose:
N 2.65 (your current dose)
P 0.35 (use this)
K 6
Mg 1
Fe 0.4ppm from csm+b trace
use this instead, your current dose of PO4 seems very low compared to the N. you do not have to worry too much about the livestock while using Urea under your water parameters. you could be adding 0.5 N daily from Urea and consider it a safe dose if you wanted. also it would be wise to keep the 1 ppm Mg because you are dosing much higher N and K. no need to add Fe DTPA to this Mix as it will further affect the Fe and Mn ratio. I still encourage you to try a different name brand for Micro and avoid using csm+b if possible.
