If you are not organic get some mosquito pellets and sprinkle on soil then water. That will kill them fast. As for a deficiency you need to get some Dutch Master Saturator for folair help. Then if you are in veg add veg nutes and some cal mag and spray heavy. That should snap them out of it.

k ill try that man thanks

It's a small red and yellow jar at wal mart.
