It looks like nutrient burn that might be causing a calcium lockout. It could also be a pH problem that isn't letting the plant uptake calcium. If this is the case, get the soil pH down to 6.5 and only use pH'd water to water it for a week or so. Then, reintroduce nutrients. Good luck.

@ernest_twwg, so your opinion seems to agree with my analysis of potassium dosage too high, rather than an excess of calcium. Thank you for the reply! I hope to receive other opinions before returning to fertilize
