Hi,
I'm new to using PPMs as a measurement for calibrating nutrient feeding. I'm trying to understand how to calibrate the additional amount of PPMs to add to soil. For example, I did a soil slurry and got a reading of ~800 ppm. I'm in flowering and want to be around 1000-1200 ppms. How many PPMs sould the next feeding be?
