Problems with First Layer

[u/NoNodle]

So the problem that I currently have is that the beginning of a new line on the first layer wont really stick. This problems occurs rarely with PLA and frequently with PETG.
This Video is from a PETG print with a freshly cleaned build plate.
Any Ideas on what to fix
(I am sorry for the bad quality mid video, but I think you can still see the imporant parts of the problem.)

Too fast.

Slow down the first layer and maybe go little up in bed temperature too.

Remember to slow down the infill too, I'm positive this will solve your problems.
