Blue berry - veg cab/new small tent grow

She looking gooooood! Love how frosty she getting. Under a microscope mostly clear but some turning cloudy I think. Realised why I've had some nute problems my cheap PH pen was out of calibration. I went to calibrate it and it just wouldn't calibrate saying 4.0 was 6.4+. So I threw it in the trash. I now have a slightly more expensive EC/PH pen. I think I've brought about 5 PH pens at this point. I hope this pen doesn't break. 3 more weeeeeeks I think till harvest, so hard to wait.
