Still if you are having to check PH twice a day something is wrong with your setup, it should be much more stable than that, either you are having evaporation issues, plants drinking too much, or your nutrients are unstable, either way your setup isn't dialed in if you are checking PH every day.agreed. set your room at whatever will keep your water temps at 65F.
the clawing is N toxicity so drop your ppm a bit. the rust is mag defic so you might want to add some epsom salts.
a supercloset is a 6 site dwc with a 2 gal reservoir. re-read first post by the OP.
Also i'd advise against putting epsom salts in a hydro rez, there's much better products to use for magnesium supplements that are actually made to go in a hydroponics system.
I'd advise to use a cal/mg supplement such as GH calimagic.
