3 of my girls were fine when they were watered 4 days ago and over 4 days have gone very droopy almost wilted real weird looking they are between 2 - 3 weeks into flowering. since the begging theyve been fed with swamp water and were doing excelent but this last time they were fed with tap water could this be the cause???? i know droopy usually means over watered but this is definately not the case here any comments would be apreciated
