yellowing

I have been fighting a mite problem with Mighty Wash, have not been feeding plants, I did miss a watering and yesterday some were very droopy, these have developed yellow leaves and some leaves are dying can't decide if it's a defeciency nute burn, light burn or what. Any help will be appreciated. the ones that are troubling are bubble kush and blue ice. Most of the others are ak-47 and they are relatively fine.

all seems well now, most are green again. can't post pics right now had surgery on my arm, i just removed the dead leaves, stopped feeding them and they seem ok
