Just read through your journal. nice Kit, good job. Are you still simply misting the top of you planters? I think you need to water them in until it runs out the bottom of the pot, them give them a few days to dry out. You want to water them really good, not just the surface. Make sure there's some runoff. Just water them bitches in.
You will find their rhythm or cycle. for many that's every 3 days. YMMV
Of everything you document in your journal. This is the only thing that jumped out at me as a potential problem.
