Counting the calmag, the NPK ratio of what you were feeding is 1-1.74-1.04. That's closer to what I would do. But, I would have the K higher. Like 1-1.7-1.7. But, it's not much difference. Some people do very high K (1-1.7-3).
The PPMs went up to 800 with the calmag.
I use
a spreadsheet to calculate that stuff. It's just proportions. Three parts this, 2 parts that.
One thing people don't immediately grasp: your Tiger Bloom (for example) is 2% Nitrogen, 8% phosphorous, 4% potassium. That's the percent of weight. But, there is a *ratio* in those numbers too. 1-4-2. (1 part N, 4 parts P, 2 parts K). If you reduce the NKP labels down to that, it's easier to compare and understand what the plant is receiving.
The spreadsheet shows the "new NPK label" (the percent of weight information) from mixing bottles (as if you could buy a single bottle containing what you create by mixing bottles). But, it reduces that info down to the proportions too. To me, that's more useful information. It's easier to understand (visualize) what the plant is getting. (The PPMs are the strength. So, you don't really need the strength-oriented NPK numbers on the label.).
