Zombie Kush x Purple Punch Micro Grow

9 day after 12/12 and still no sufficient stress from the plant it's just grow like normal. Might be she's not in the size to bloom because of my slow veg earlier. Change the light from led bulb to quantum board and dimmed it to get around 35000 lux at this moment. This is the first time in this grow i water with the run-off Solution: 550 ppm 6.2 PH / Runoff: 1500ppm 5.9 PH (Soil grow) run off ppm quite high but didn't notice any toxicity or deficiency should i flush her next round ? or just keep the schedule plain water then feed.
