Hey guys looking for a little help. Running in FFOF temp is 78 degrees humidity at 65 percent in late Veg with the ROI-E680 recently increased lights 2 days ago from 45 to 50 percent and 2 feet from top or canopy
Running RO water been feeding cal Mag in every feed and just saw these signs on the leafs appear. They are dry and I’m about to feed again. Ive been doing the lesser mL/ L of cal Mag should Increase?
I feed 770 PPM going in pH 6.5
Run off every time is around 1800 and I know they say don’t stress in FFOF because it’s a “hot“ soil. I feed feed then flush.
Looking to clarify this is Cal Mag def. Or light stress?
Im decreasing lights 5 percent to see if it helps a little bit.
thank you so much all! Also this is showing on majority of plants.
