It looks like you need to get yourself some type of Ca/Mg supplement. You are under LED and that alone raises the Ca/Mg requirements. If you are using RO water too, this really raises the Ca/Mg supplement need. Your are at a critical stage to keep your Ca levels adequate. The flowering stage is when most people run into Ca/Mg issues as the buds are using it up so fast. This would be a great time to start giving her some P/K boost.
