So I’m getting close to the end of my third successful grow and I’m still kinda confused when it comes to the whole PPM stuff. I have a PPM meter and I’ve tested my runoff the entire time in multiple different ways suggested to me and throughout this whole entire grow my PPM has never once been above 300 yet my plant seems to be doing just fine.... does anyone have and knowledge for me haha
