PPM should stay static, or the same. If PPM rises the plant is ignoring nutrients and drinking the water. Loss of water and nutrient amounts stay the same, and the PPm reading goes up. The PPM will never fall unless you add water to the reservoir. Always top off with the same mix /ppm you used during the current swap.I don’t know really what I’m doing with ppms. All I know is that it is a useful tool when using nutrients to read the plant as well as what I put in her. Like just before my last rez change I noticed ppms weren’t dropping within a 24 hr period so I did a res flush and cleaned everything out. As soon as I started putting nutes after the res change she started eating again. I think she was in a lockout situation with too many salts from nutes but I could be wrong idk. Imo She should always be eating ppms so if she isn’t then something ain’t right imo. This is just my experience with the relation to how she grows and looks. I can see an immediate change in her visually when I do something different. I use all the tools I have and play around mostly just to see how she reacts I then use the thcfarmers members input then I use all that information to extrapolate future decisions to make her happy. In summation I find a base to work with, then I fine tune all of my resources in relation to how she responds. If she’s growing, green and smells nice then I’m good or should I say she’s good.
exactlyBro, I’m new but I’m not positive you’re reading your PPMs correctly. It’s my understanding if your PPMs are dropping that means your plants needs more nutes.
If PPM stays the same as water level lowers, that means the concentration of nutrients in the water is well balanced and the plant is absorbing it.
If PPMs rise that means your plant is taking in water but not the nutes because it’s too much for your plant.
If I’m wrong, please school me.
lol, I read the labels on the back of the nutrient labels and added for aggressive growth. May have put a few ml too much but heck man she grew a lot sinceShe looks healthy! Huge jump in PPM, why the change?
