Does Clearex get pH'd?

Hey all! So I think I may either have a nute lock out, or I overdosed them with too much CaMg (leave edges are slightly buckling towards light). So to try and solve the problem all at once, I plan on flushing with Clearex. My question being, do I pH correct the Clearex solution before flushing plants?
I grow in soil, my plants are a little over a month old, and in 2 gallon grow bags at the moment. Before adding the CaMg+ from GH, some of my plants leaves were getting rust colored spots, and yellowing. Thanks to all who reply.

I'd prefer to see some pictures to help diagnose the problem or confirm your diagnosis, but short of that....... You always pH correct your reservoir/solution/whatever after nutrients and any cleaners, h2o2, etc are added. So once you dumb your Clearex in there, add water to bring ppm where you want it if necessary then adjust pH. On big reservoirs over 20 gallons always wait 10 minutes before using the water to ensure an accurate pH reading as all the additives to the water mix in slower for more water.

Good luck!

Thanks researchkitty for your quick response. I will try and post up some pictures shortly. I am using a friend's computer at the moment, mine crashed more then a few weeks ago during my first 'online' grow journal, but will be getting mine back from repair later today. Thanks again.
