Solved my hard water issue for now. I wasn’t checking my starting water as much lately and assumed my water softener/filter was good to go but when I finally read what the tap water was i got a reading of 500ppm. Changed my filters out and now starting at <10ppm tap water. Ran a decent amount of runoff out of the plant but plan on giving this plant a proper flush with ~800-900 ppm nute solution this week. So far the plant has been topped twice.
Update after the flush, the plant is definitely doing a lot better. It is growing a lot faster now and currently is the biggest plant in the tent. Theres already a few inches on the side branches of the second topping sites. Purging the soil of excess salts and nutes showed a noticeable difference in growth rate. This is the strain I am most excited for this grow cycle
