She looks overfed (nitrogen) to me. Do you know your runoff PPM?
No but next watering I’ll do just plain water ph’d
You should always have runoff when you pour liquid into your pot. Each and everytime you water or feed record runoff ph and ppm. Tracking helps prevent issues by alerting you to your plants activities. Also…feed, water, feed, water etc…
Agree with @MidwestGuy. Liberal run off and let a cup or so run out the bottom then catch a sample. Salt build up in the root zone could be preventing certain nutrient absorption
