I don't change my res
Ya I really think the low humidity is what caused the problems, so now that that's fixed me and the plants are super happy. They're eating again
pH won't fluctuate...

UC Roots is hypochlorous acid so it won't instantly turn into chloramine in the presence of fertilizer. It does degrade into hypochlorite in water, which is then quickly converted to chloramine in fertilizer solution. The important point is that the standard 8 drops per gallon of bleach (or 4 ppm) of hypochlorite cited for sterilizing water will not work in a nutrient solution.
Chlorine equivalency of suggested Pythoff (chloramine) use rate is 29 ppm.
UC Roots use rate for weekly treatment when water is 68F or below is .22 ppm hypochlorous acid.
This (weekly use) does seem to indicate hypochlorous acid is a good bit more stable then hypochlorite in water/nutrient solution. Also that hypochlorous acid is a much stronger sterilizer than hypochlorite and that hypochlorite (in water) is about 7x more effective than chloramine.
But... yes, they're all chlorine products. Effective use rates will vary based on the form of chlorine used. I was originally thinking that UC roots might be a good choice for clones in a non-nutritious medium, but as it converts to hypochlorite it will evaporate, while a product like pythoff should remain in solution longer regardless of whether nitrogen is present.
To get the same chlorine equivalency as Pythoff in a nitrogen containing nutrient solution from pool shock (65% chlorine by weight) one would need to use 45 ppm pool shock. Note: 45 ppm pool shock in plain water (no nitrogen) would be very high and likely damage roots. Whether this is all scientifically correct depends on the quality of information provided, but it does indicate hypochlorous acid is about 130 times more effective than chloramine and 7 times more effective than hypochlorite. Stability issues aside (which could be important) it's good to know which form of chlorine you're dosing with and what the effective rates are.

Want to show you guys the plants since adding UC Roots.
Don't wanna give too much credit to "pool shock" tho. I also got my humidity in order, which is more likely the reason for all the growth and sudden feeding frenzy...650-545 ppm in about 12 hours.
Lots of growth from original post
Thinking of putting a net up...may get too much bud tho.
jk hehe
