Water droplets on leaves
Sounds like they are aspirating (losing water)
Spray with a fine mist of water, or even a VERY low dose of nutes or foliar suppliments like Nitrozyme, Green fuse, liquid Karma etc....
(move lights WAY up or turn them off for an hour while they dry!)
Make sure they are being watered/fed correctly and that the humidity in the room is not too low.
No need for revenge, just sit back and wait.
Those who have hurt you will screw eventually themselves; and if you are lucky, God will let you watch!
Through What we create- we are immortal.
