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?

It works like that in hydroponics not soil!

Man o green is right. In soil you shouldnt really be going above 600-800ppm. Soil holds nutes where as hydro and coco do not which is why measuring is so important. It is in soil too but you will get a slow build up if you keep feeding so heavy.

I got a N tox during flower and it caused a magnesium lock out, it took a month into flower to show. MOG is definitely the person to advise on this situation
