I started my germination process last night in Rapid Rooters and used a pH up that took my pH to 10 and then used pH down to 6.34. I'm now reading pH for hydro should be lower.

Did I mess anything when adding that much pH up? The nutes were already in the water, could this have caused anything to happen to them? I was only using a light bloom at 240ppm.

Should I attempt to lower the pH now? Or it not a big deal and do I run this risk of over soaking the Rapid Rooters?

I was worried that pH may have drifted up so I tested again today and it did, 6.8. I discarded the water and have a made a new solution with water steady at 5.5, no bloom this time. The ppm had drifted up to 280 as well! I'm currently trying to try the Rapid Rooters out so I can add some of the new water, I've taken the lid off to lower the humidity and put a Heater/Fan blowing on the tops of the RRs. The Electric blanket is working perfect and is keeping the tray at roughly 75-76 degrees.

Does anyone think I risked "damaging" maybe even a couple of germinating seeds with this slightly high ppm and pH? If so does anyone also thinks its worth putting a little fresh water on them now?

i wouldnt worry about it too much,ive germed in beer before.
