Plus me committing to purposely offing my nutrient uptake sounds like a horrible idea. I know if you have heavy ph swings you can add ph down, and then ph up to increase your alkalinity in the water, this also increases ppm yet doesn't count really as the nutrient ppm your trying to monitor. I also noticed a huge increase in ppm when I added my enzymes, and I only added 1/4 the recommended dose. I also noticed depending which blend I used, it changed the ppms needed. If I want to run transition blend I can use 300ppm, but if I switch to bloom blend the same day, I will need it at 400ppm due to it being different ratios. Hell I could over feed veg blend, defoliate everything, then lower feed and go strait to bloom blend without transition. As long as you monitor the plants uptake and dilute, they will pretty much thrive in anything... Regardless of ppm. The amount of light entering your system dictates how much algie is grown, dictating how much nutrients the microbes are absorbing and not counting what your plant is absorbing. If you have a large colony they will be feeding off your nutrients as well lol..Sorry, never knew this was just a picture show of your grow
I'm just suggesting it's near impossible to understand someone's ppm method. It's so different with every grow.
