Alkaline PH of 8.1 in part of soil, caused nutrient uptake problems in one plant, gave the other time to catch up, added aluminum sulfate to remedy.
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.
Remedied with aluminum sulfate, things seem to be coming back to normal.
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.
