I know you are working with some others here so don’t want to make it too crazy. Personally I watch the soil as much as the leaves. If the soil looks moist on top I for sure don’t water. If it’s dry on top and I wipe away the first 1/4” or so and it’s moist I don’t water. If I sort of poke my finger in there a little deeper and it is fairly dry around an inch or so I will water with about a 1/4 to 1/2 gallon of water depending on when I watered last, condition of plant etc. As far as nutrients I run them approximately once a week and then ph my water and add some
calmag as I have water with heavy lime. What nutrients are you using? In regards to the watering aspect images of your soil would probably be better than pictures of the plant. A pic of the top of the soil and then a pic of the soil with the top half inch to inch in a small area pulled back.
