Planning on flipping one of my plants this week so I flushed it this morning because I think I'm supposed to. PH and PPM were both low. After the first runoff PPM was 115 and PH was 5.5. After the 3rd gallon of water ppm was 115 and ph was 5.3. My input water is 170 ppm and 6.3 ph. It's in a 5 gal pot with 50/50 ocean forest and happy frog. Been feeding once per week of FF Big Bloom and Grow Big at half strength. After flush I introduced Tiger Bloom to begin the full trio. In my feeble mind all I can surmise is that the plant is depleting all the nutes I'm giving as well as what was in the soil. Also wondering if I need to up the water ph to compensate for the apparent low soil content. Feeding ppm have been in the 700 range throughout.
