You are experiencing progressive potassium deficiency. Light nitrogen and heavy potassium are phosphorus in flowering. Good luck🌱

Burn, deficiency or other?
I’m completely stumped as to why my one plant is showing signs of deficiency or burn. Used the exact amount of fertilizer per plant. One plant is fine and the other looks terrible. I used a half dose of cal mag and it seems to have stopped but is not drinking or looking better.

I've noticed for a few days that the leaves of the plant are turning yellow or looking like in the photo. I'm not sure if it could be some kind of deficiency or lack of nutrients since I haven't fed it more since the last time, and it's taken on a lighter color.

What kind of deficiency is this or is it light burn? Can provide more pictures since they are in a sleep period now. It’s this plant, strawberry banana one and the purple queen.

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?
