PPM. 6/6,5 PH waterings or too frequent waterings?

I grow in coco a lot. .1 ph in coco is a huge difference for plant. So In vegging ph water in 5.8. Run off ph 5.8. 5.7 or lower is lock out. In flowering I do a 5.8 in, and a 6.2 out. 6.3 and up is lock out. If ph spikes up your not giving enough nutrition. If ph spikes down it is too much. In run off measurements. Coco follows hydro rules. Cal mag is required in coco grows. Coco should stay heavily irrigated and always wet. Do NOT let sit in run off. I run 2 gallons minimum through my plants every other day unless ph is off then I run more to adjust ph in run off. The run off ph will tell you a lot. It is only run off measurement I use and I have amazing results in my autos lately. If you have more questions feel free to dm me after selecting my answer.
