Doubtful, as humidity is reportedly too low.

Most likely it's an overnute situation, or too many additives. If you were to list all products you use, quantiities and schedules for you vegging ladies, and your flowering ladies, I'm sure we can figure it out. (will require seperate details for each light schedule) :thumbsup:
