It appears to be a problem with magnesium uptake. Whether or not it's a lockout or deficiency I can't say 100% but based on the tip burn I'm leaning towards lockout. Try a foliar spray.
Without knowing the details. Like what media you’re in. What kind of nutrients you’re using. It’s a little hard to ay exactly. But I can say it seems like you’re going through nutrient lockout. Just my opinion
Without having all the details ( please remind me if you have already told me lol...i am a stoner) its kinda hard to narrow it down....are you in a super soggy media?....could be water logged or root rot forming. Could be toxicity to nutes. Not sure what schedule you're on. Are you feeding full strength? How often?
Could be PH issue...that would cause the needed nutrient to NOT be available to the plant. cause at whatever ph you're at there may be no cal/mag or phosphorous available for instance. Hope that makes sense lol
