Hello all.
Quick question here.
My method is hand watering to waste. I mix up about 3 gallons of solution with nutes and balance to about 5.9-6.0 (in coco). Have to use PH Up to bring it up there after the nutes are added. Last night, after using about 1 gallon I re-checked the PH of my solution just out of curiosity. After about 20 min it had risen up to about 6.2. So I added some Down to take it back down to 6.0. 1 gallon and about another 20 min, it's back up to 6.3. This is all in the bucket of solution, not the runoff.
So, after using the entire solution up I mixed another 3 gallons. Did not use any of it as an experiment and just let it sit there. 20 min later...it's up to 6.2 again.
Why does this happen to solution just sitting in a bucket??? Anyone else have this happen? I backed up the results with test strips and re-calibrated my meter with the same results. I even replaced the probe on my meter just to make sure. I use Botanicare nutes and honestly don't know if this has ever happened on the previous projects. Does PH UP take time to dissolve or take full effect?? The only difference from this and previous projects is that I am using a lot more water than before...does that have an effect??
I'm very confused and am wondering if this is causing some minor issues I am having. I can't understand how I can balance a nute solution to a particular point, and 20 minutes later...without using any of it...it jumps up at least .2 points. To top that off, I let the new batch sit longer, and the PH just kept rising.
What the hell is happening??? Will it ever stop rising? I decided to let the new solution sit overnight just to see how high it rises in 24 hrs.
Also, this is with RO water starting at 7.25 if that helps.
Thanx for any insight.
