Got some kind of like burn in some kind of nutrient problem so I bought $150 a parameter tired of the generic cheap p.o.s.still overall happy with the grow it'll be the most weight and best looking stuff I've grown yet
measuring ppm runoff in soil can often be tricky , i would buy a bunch of cheap PPM meters (because they break often) and see for yourself, you definitely do get more control if only because you start measuring your inputs aswell. Hope this helps! 🚀
