It looks pretty good. pH is neutral and looks like most things are in normal range.
What hydroponic solution are you using and are you going to have a metering system or do a simple solution change. Remember that the nutrient requirements will change with different growth stages.
This is a sample nutrient formula for tomatoes in Florida. You would need to adjust for the water quality you have. https://edis.ifas.ufl.edu/cv216
