Canopy about 30 cm above 100w ufo. I don’t have room for my 600w atm. Ph is between 5-6 and I’m using mills a+b with canna cal-mag and budlink silica. Now n then I use nitrozyme in my coco grows. I’ve found that my mills bites mix up fairly acidic if I go over 800ppm. Like down close to 4.5ph without adding any ph down. Never seen that with house n garden or advanced.
