Wow thanks everyone for your valuable time, i really appreciate you experts help !
It seems to affect the older fan leaves first. But then even the new leaves in the buds will start to do it as well.
It affect all the strains I have mainly the same. I get some of this in Veg as well so fel it maybe a common problem in my water mix up.
I have tried just adding only 4-5 ml cal mag to my R/O water and feeding that only as a way of letting them settle out ?? Maybe recover a bit ...Just grasping I guess.
I was always told to back off and go easy if you see trouble. So i have been mixing less nutes for feeding and less
cal-mag in both watering and feeding cycles. In other word easing up...maybe that is wrong..I just don't know
I'm from Canada so the products are not familiar to everyone...I put the links to them here.
Nutes I use are
DNF Formula for Bloom part A & B and in veg the Part A & B
DNF Bloom fortifier and veg fortifier in veg
Or Monster Bloom instead of the DNF bloom fortifier
Cal- mag
I was also using Super Thrive but it has become unavailable here so switched to this.
Aussie tonic. It's supposed to be the same as Super Thrive
I was using this as well but have backed off in an effort to simplify things
Dense
Those are basically my nutes and I use some Carbo sweeter product lightly that acts as mollasses would I assume ??
DNF Carbo Logic
So basically Start with Ro at 0 TDS and after adding
DNF part A & B
DNF Bloom fortifier
Cal- mag @ 5 ml per gallon/litre
DNF Carbo logic
I end up at 700-800 TDS
Oh ya and always PH it all to 6.5%
