Before you do anything, there is an important diagnostic step that will reveal any problems with your bed adhesion. I did not see you mention performing a first layer test, so I assume you are not familiar with it.
Do you think your plate is clean? Do you think you have the right settings? Do you believe your bed temperatures are dialed in and your filament is tuned? A first layer test will quickly reveal any issues with build plate hygiene, filament extrusion, and flow rates, all without using much filament.
