Check the PH on your runoff. Looks like she might be having a nutrient lockout. If the pH is fine try supplementing some cal mag in. 🤘😤

Browning leaves? Did a soil slurry and dropped the water from 6.8 to 6.2. Does that mean it’s locking out? How should I go about fixing this? In peat pearlite and worm castings. Added about 6 cups of lime to the 20 gallons of soil thought that should have helped the ph?
