Blueberry, Girl Scout Cookies,White Widow, and cantaloupe haze

I installed a PH controller but it didn't work right and only the ph up peristaltic pump is working. I will use this over my vacation as my PH drifts down naturally so this should work until i get a replacement. I watered in my gsc and other seedlings until runoff with 850 ppm heavy in nitrogen to green them up as the organic top dressing is taking too long.will see how they respond
