@Hungrybud yes I forgot about that thing, I got pissed one day because I kept getting my hair stuck to it so I moved it up lol.
I had some suspicions about my ppm meter so I ordered a Bluelab ppm/ec meter to see how close they were (plus it should be a better quality pen than the Honeforest meter). There is an 85 ppm difference, the honeforest reading lower. May have contributed to the overfeed/buildup on the last grow. In any case, they are looking good.
900ppm, runoff are 640-850ppm. Did some LST, topping and Supercropping so they are a little frazzled at the moment lol.
Good catch. Nice Buy
