How many PPM the Run-Off must be if i give 650PPM?
I give them 650PPM nutrients and i saw some curling and yellow tips, so today i flushed with RO water at 5PPM and my Run-Off was 900PPM.

so first off, PPM is just a measurement right? it means parts per million, it doesnt test the quality of the parts , get it? what i'm saying is that there is "dangerous" high PPM and "no problem" high PPM , for example i watered with 900 PPM yesterday but it was only micro nutrients and some bacteria , so basically the high PPM doesnt really matter ... But PPM does matter for the nutrients , so you need to measure your nutrient PPM, that means part A + B, B52, voodoo juice, ... that's the important PPM, and based on the measurements, i do think that you are OK, not too high, dont worry. So what 's the problem ? basically i see overwatering is the problem, i can see that from the leaves having puffy space between their veins and how they are curling down. so you need to follow a strict wet-dry cycle , make sure you let the medium go dry before watering again, maybe wait 6-7 days and water again. Yes, it really is so simple ! I hope this helps ! :rocket:
