Too Much Ph chemical in Ebb & Flo System

[Ecto06]

I am using Advanced Nutrients line of Ph up & Ph down products with my ebb & flow system. I'm in 4th week of flower. Is it possible to use too much Ph balancing chemicals in one evening even if the end result is getting the Ph back to the ideal level of 5.8 with the PPM at 1300?

Yes it is, by doing this your medium can get a build up and ph can get off there. Check yourmedium ph and see if thats the same. if not adjust to bring the medium to 5.8
