microbes and ph

For years I have used the Lucas Formula with cal mag iron silica and kool bloom. I use RO water. When I mix correctly the ph is always 5.5 and I have never had to use ph up or down through the whole grow. I recently decided to add orca microbes, sea green, rootamentary and tru blooms from beneficial biologics. At the end of my last grow I added orca and it made the ph keep going down below 5.0 but that was easy to fix since ro water comes out at 7. Now I started a new grow with all the microbes and the ph keeps rising. about .25 an hour. I wasn't expecting it and my plants almost died 1.5 days after new water with microbes. I have had to dump over 1ml of ph down every 8 hours in the 3 gallon buckets. It is now 6 days later and I am down to 1ml every 15 hours but it still climbs.

I asked the hydro store and called BB.. both say they can all be used together. there are only endo's in it, no ecto's or tricho's. I am using water farms with hydroton. Everything is disinfected with hydrogen peroxide thoroughly like I've done for years.Never a bug or disease to this day. So the only thing that changed is the addition of microbes.

Has anyone else had this problem? How can I fix it other than adding 200ppm's in ph down? I am considering trashing the microbes since 2 different environments and strains.. both times caused ph imbalance. I'm making new ro water now to change everything out.

Awesome. I will have to try that. I kept kool bloom out of the feeding cycle right now because they're veging. I'll try it out.
