Ok ok wasn't challenging you or anything just seemed really sure of yourself considering they're not the clearest pictures. It's usually advisable to put 'in my opinion' or something at the end so people don't think you're DrMcSkunkins or something like that and just blindly act on the advice. I would have leaned towards nitrogen toxicity because there's a fair few yellow tipped leaves there, and they appear to be clawing rather than drooping, and the overwatered plants I've seen, EVERY leaf drops. The question is whether it's because of overfeeding, or whether there was some sort of lockout that's suddenly been fixed and released nutes I.e nitrogen in abundance. No expert here, please research this yourself and ask a few of the pros @Dewd
