   I think that might be a potassium deficiency. Your plant shows no signs of cal mag. Extremely green growth, no yellowing, and no rust spots/necrosis leads me to believe it’s doing fine in that department. Raise your ph to 6.3-6.5 for a bit and feed half strength of your normal mix if doing high ppm. Phosphorus gets chemically bound at around 5.5 and lower. Then bounce down to 6.0 for the duration. Peace.
