Surprised by how well the water is wicked to the medium from the water bottle, it took a long time, but RH% works as intended. I was unsure how much if any nutrient would be transferred via wick but the high salt content altered pH at certain parts. Right before the symptoms arose I decided to supercrop the stem top to bottom on one plant, shortly thereafter the burning happened from same plant from running 8.0 pH , and nutrient uptake ground to a halt on the same plant that was dealing with stress. She really doesnt seem happy.
Remedied with aluminum sulfate, things seem to be coming back to normal.
I need to be more careful with salts, verrry base.
How many weeks shall we veg? Going to take a while to fill that canopy with just two plants, should probably start topping now but I'll wait until pH problem Is remedied first, a couple more days hopefully 🙏.
My own hubris.
I defoliated maybe 6 bigger leaves that had burned yellow on one plant, as it comes back to optimal range, this will be a good opportunity to observe the subtle differences that early defoliation can make.
