Nice work. I really admire your hardware setup. However it's worth adding that most of blooming plants will change their 'diet' during their flowering period. Some will continue to grow through the whole cycle on one mix and other (like tomato, cannabis) need some additional nutrients dj'ing. I've been growing succesfully 'passiflora edulis' in hydroponic setup for 3 years (continuously) and still I'm using hydroponic as a great kindergarden for most of my new plants.
