imo u need to test run off of each plant that is having problems
I watered this morning with 1/2 tsp of Jack's per 4 gallons. Double what I had been using, but still only half of what the instructions say. I also added 2 tsp of
Cal-Mag Plus to my 4 gallons of water, which is 1/2 of what
Botanicare suggests for soil. The
CalMag seems to have lowered ph a little. Instead of the normal 7.5 after nutes, it was 7.2
Given the mixed opinions on whether or not I should be using ph Down, I still used some, but only enough to get the ph down to 6.8 instead of 6.4 like I had been doing.
I checked runoff of each plant individually.
One Pineapple Haze was at 6.2.
One Blueberry was at 6.5.
All other plants were 6.3 or 6.4.
The plants with the brown spots are my 3 Pineapple Haze and the one Blueberry that was at 6.5. On the Blueberry, it's only affecting one or two leaves.
Since it was mainly affecting the Pineapple Haze and not the Blueberry or Strawberry Kush, anyone have thoughts on what Sativa dominant strains (or Pineapple Haze specifically) might like more or less of vs the other strains?
