Auto Blueberry Fem from Errors Seeds

Hi Friends! Great experience so far! Day 30: Watering ppm100 and pH 6.0! My babies are eating just fine! Drain pH 6.3,ppm 590 to 890! Plants are crazy big. All of them are females. I need a bigger box for the 3 plants of Blueberry. Day 33! Used juice Advanced Nutrients pHp: 4ml/l+B-52 2ml/l and for the flowering plant - Advanced Nutrients pHp 2мл/л+VoodooJuise 2мл/л+BudIgnitor 2мл/лBudCandy+2мл/л. pH is 6.0. Drain is higher ,pH6.5, ppm 340 for the middle plants, ppm 520 for the right plant, and the flowering shows pH 6.4, ppm 710!
