Repotted into a 3 gal airpot and buried the stem, switched to veg nutrients. Still not in my final grow room and without humidity control I had a really high VPD. The plant adapted well anyway.
Reusing very old and depleted coco I pasteurized but did not bother rebuffering, so I'm adding extra calmag to my watering schedule. Watering bi-weekly. Old degraded substrate hold way too much water at this stage.
