Ok more details.
First its a soil grow.
Second, I'm on well water for source however I do run through a RO system.
Third, I have a water softener and the RO system is after the softener, could it be a salt issue in the water?
Fourth, The nutes and water have been the same as long as I have been growing, which has been awhile.
The plants seem to be growing and flowering ok but I have never had this issue before. Could it be heat related, as temps here in the north have finally gotten warm? This is the first year of flowering at my site so I dont have previous years experience but have ran the veg cab for years without a problem.
Thanks TF
