The last couple of times I mixed up CSM and added HCL the result was a fair amount of mineral scale of some sort in my mix. No fungus but I'm not real happy with this new stuff either. I'm adding 5-10ml of 31% HCL per 500ml of fert solution at the end, after mixing the CMS and water. Is this normal or am I doing something wrong?
Noticed some talk about adding Excel to the mix too. Does that work to curb fungus in the fert mix or is it mainly to prolong Fe availability?
