Your queen looks great still, deficiencies happen due to lockouts, maybe there's some mineral locking out the other or maybe that they're still hungry? Whats your DLI?
@theplantdaddy, so you suggest to cut all crispy purple leaves? Just to clarify if I understand you correctly. And new leaves would still develop although she is in middle of bloom?
@MrMunchi, any chance you could feed a basic salt fertilizer at about 400-500 ppms? I'm sure they can still go longer and results may be better. I would suggest a top dress but that'll take a couple days to kick in
