I lowered it a bit. The ratio of cal-mag and my nutes gives my res a pH of somewhere in the 5.0-5.5 range. I will check the substrate later and if its really high i will lower the cal-mag a bit more. For now everything is in check.

the ph of the substrate was around 6.5
I think I do need to lower the cal-mag way more.
i will do so soon and post here if it had an effect on stabilizing my substrate. It is just crazy because my res is low. like 5.0-5.5 and the substrate so high. It must be all the cal-mag they are not drinking.
