Follow the basic chart with Cali-magic as the only thing extra. RO water.
Keep the PH within 5.7-6.2.
The PPM is as mixed. Drain to waste (Coco). If you mix accordingly to the chart using RO water. There's a ppm that falls in between the listed ppm range.
Example.
I'm in early flower. 4ml,1ml,5ml,2.5cal to one gallon. The ppm comes out to 620-630 (How accurately I measure the water). The chart shows a 500-700ppm range. To adjust it is a process.
If you follow the chart. Follow the instructions. Its damn near perfect. Excellent growth. No burnt tips. Happy plant.
