Strange layer separation issues on Ender 3
Well, you have several problems with your print. One that could be affecting your print is the nozzle temperature. The print looks wavy and has a lack of adhesion, so the filament is not flowing properly, causing under extrusion and will provoke a clogged nozzle. 

Try to increase the temperature by 5°C and do a small test, don't wait to waste material and try another 2-3°C more. 

Try to reduce the printing sped; try reducing the feed rate on your printer to 90% or less. While printing you can reduce the feed rate to see which speed works better at your printing temperature. I prefer to do this first rather than change the temperature; If you notice that your print gets better at lower feed rate then change your temperature higher to print a higher speed.
