Well, what I thought was a nutrient issue with the mix I added to the soil, has actually been a ph issue within the medium :/ I used one of my old soil probes to check it before I transplanted into it, but it must have been way out. I did a run-off test and the ph of the Critical was 5.0. My solutions have always been 6.5 +/- 0.1. And my ph pen is calibrated correctly. I've flushed it completely with filtered water and added some dolomite lime to bring the ph up. Hopefully it starts to pick up again. ph run-off now at 6.2-6.6. The critical didn't really show signs of stress like the Haze-Berry so can already tell it's a much more hardy plant
