Well shit..... Here is a reminder for everyone out there, calibrate your pH monitoring equipment on its recommended schedule! Of all the things to forget about. Sigh. My pH has been out of whack, looks like it was far to low and I have been effectively starving the plants of phosphorus. At least is what the leaves are starting to show, a definite deficiency. It was hard to see on the right plant at first as the purple hit the spots rather well. They just started turning necrotic in places. It really jumped out on the left plant and was easier to spot. It was reading 6.1 but was more like 5.2 Lesson learned, stay on top of that pH. I think it is time to retire these old Milwaukee MC120's in favor of some newer models. I could just replace the probes and double down on the calibration but I've had these things for nearly ten years now. I think sitting in that moderately humid environment has taken its toll on the internals. They aren't exactly made well. Oh well, these won't end up looking perfectly pretty in the end I guess. Given that I already wasn't to happy with the pheno, I'm not expecting much from these plants now.
