[Cooterjuice]

@Mañ'O'Green this has progressed since Saturday. My first thought was underfed. Upped ppm, 500 scale. From 550 to 700 over 2 days. Ph has been 5.8-6.0. They asking for magnesium sulfate? I have botanicares fancy liquid stuff they call Sweet. Pics are in order of progression. Feeding Botanicare Kind nutrients.

Looks like too much potassium (K) to me. I am not familiar with the Kind line? Are your PPM numbers including your starting water or just the nutrient strength? Are you recirculating or feeding to waste?

Yea using ro water 700 ppm final strength. And feeding to waste. Fertigating twice a day. Not quite a gallon total between both plants. Getting almost a qt of runoff
