Auto Blueberry Fem from Errors Seeds

Hi Friends! Day 22. I used juice Advanced Nutrients pHp: 3ml/l of Cal-Mag-Pro, 1ml/l. I am not sure about the numbers because I think my meter is broken: ppm joice 780, ppm drain 800, Ph 6.2. t- 25-30C, hum - 50-60%, Light = 500Watt. rearranged plants in the box. I want to tell you about my DIY! automatic watering system - hope it will work. My seedlings showed their sex!
