My entire grow my pH has increased over time. Roots look amazing, clean & white and Res temp at 20°C. Im now in week 2 of flower and my pH suddenly started dropping a few days after a reservoir change. Tent day temp 25°C, night time temp 19°C Humidity I try to keep at 45% but it fluctuates between 30% - 60%. im using 2 mars ts600 in a 20"x36"x62" tent.
My res is 5 gallons and I use GHE flora Trio: 24ml Florabloom, 16ml Floramicro, 8ml Floragro, 10ml Rhino skin and 10ml UC roots, then 3ml 20% phosphoric acid to bring down my pH. After res change: ppm 563, pH 5.9. Day 1 after res change: ppm 548. pH 6.1. Day 3: ppm 507 pH 6.3. Day 4: ppm 539 pH 5.92. Day 5: ppm 585 pH 4.5. It was directly after this reading I pH'd to 6.2. Haven't had a chance yet today to recheck my pH as my lights off cycle doesn't end until 7pm.
