I think 3/4 tsp KNO3 and 1/4 tsp or a little less of KH2PO4 would be better. I ordered some TMG (Tropica Plant Nutrition Liquid) from Big Al's too, to try instead of CSM+B+extra iron. But, I will keep my CSM++ until I see if the TMG is better for me.turbomkt;12956 said:I'd be guessing without looking the numbers up, but 1tsp of KNO3 and 1/4tsp of KH2PO4 sounds about right for macros.
Also, consider what was formerly called Tropica Master Grow. It's now Tropica Plant Nutrition Liquid. Big Al's has it here.
I know CSM is cheaper, but I've been using it for a couple years and am ready to change what I'm doing. If you want to try CSM+B, I've got some extra I can send you for a test.
When I bought my CSM mix from Greg he was selling a version with extra iron in it, but I don't remember how much extra iron it was. Then, I understand, he found that the extra iron wasn't necessary, so he quit selling it that way. Maybe he will read this and respond himself?Mooner;12961 said:Hi VaughnH,
About how much extra iron do you use when mixing CSM+B+Iron. I have used extra iron with good results but not sure of the dosing. FYI my substrate is inert.
Happy New Year
