People with recirculating reservoirs, how often do you change the water in them? I have read/heard both 1 week and 2 weeks. I will be changing every week with the Foothill Hydroponics trifecta of grow, bloom and hard water micro I am using because the label tells me so. I assume uptake varies between strains, temps, fertilisers, chemicals in local water, et cetera ad nauseam.
