need alot more info bro. Using tap water? RO? What light? What kind of nutes? Whats the environments temp like?
IMO using ro eliminates potential problems. If you are using ro, check the filter, test the water.

In addition to what rocknratm asked I want to add.
What kind of soil?
How old are they?
What is your watering schedule?
