As image reaper stated, more is not always better. The line up you are running is very similar to what I do and I imagine it should be working quite well. The only think I would recommend is maybe using Nitrex to correct/boost your N levels. Some sort of carb load at the end might not be a bad idea either. Also, adding some aerated compost tea will boost your uptake considerably and can allow you to reduce the amount of fertilizer that you are using.
