So, I'm three weeks into flower and my soil pH is 7.2, and it's climbing.
At transplant (about a month ago), pH was about 6.6 or so. Two weeks ago, pH measured about 6.9-7.0.
The trend is increasing, but what can I do about it at this point? I'm watering with RO that's about 7.5pH, should I start bringing pH down when I water? If so, what's the best thing to use to accomplish this?
It's odd because I mixed up more soil than I needed for this cycle and the unused soil is at 6.7pH. So, something is going on in these containers. I'm assuming this soil is bacterially dominated and large amounts of P is inaccessible without solid fungal activity.
Plants are looking good at the moment, but I'm sure yield is going to suffer...and if pH continues to climb I'm thinking things could make a real turn for the worse.
Any thoughts?
