Hi, I don’t know PPM, but I have a RO system that I’m going to use soon.Nothing wrong with chlorine in your water,do you know the ppm of your water? And what its made up of?
As said already above,lift these pots out of the trays,elevate them so runoff water cant get sucked back up.Mix up some food with calmag and pour it through.
Your plan/food so far is not good.
Yes, when I top water them, I take them out of the trays, empty the trays. Place the pots in the bathtub, water them. Let the run off flow away.. wait some more… and then I place them back in the trays and turn the autopot system on again.
Don’t chlorine kill the bacteria? I grow organic…
