not sticking

Hi does anyone know what is causing this. The dimensions are 200mm x 200mm I have a glass bed set to 65C and the extruder is at 190C Everything was calibrated recently. (it did this before and after calibration) The bed is level. The glass bed is secured with double sided tape instead of clips...

So, my new ender 3 printed the first 4 things pretty well. There was a bit of stringing but otherwise they weren’t too bad. I then changed the filament to black PLA and suddenly nothing would stick to the bed. Can someone tell me what I should be checking. I’m running the nozzle at 190 - 200...
