Need another opinion or 2... what do you think? Boron or Calcium deficiency?? I'm at a loss as to which one it is.
Week 5 of flowering at 12/12.
Growing in soil
Ph 6.3 and rarely fluctuates.
Feeding full strength nutes - Bigfoot Dutch 2 Part Nutrient 1.5-0-2.6 and 0.5-0.5-5.
Nutes given every second watering.
Using a 600watt HPS
Plants were doing awesome until 3 days ago....

are you using cal/mag or was dolomite lime added to your soil? If not then I'd lean towards a calcium deficiency.

none of the above and yes, my first guess was calcium as well but with these two deficiencies, they always seem to look the same. I figured I would ask for another opinion just to be sure. It sucks when you treat for one issue and it turns out to be the other... Thanks gangjababy...
