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?
