Hello. It's not good tip to solder LQFP. Much easy and faster to solder LQFP by using tip with flat surface, you can solder one side of chip by only one iron pass. What you use is bad practice, there a lot of video on TH-cam how to do it properly.
Its almost impossible to solder individual pins on tqfp. Put plenty of flux down then put solder on iron tip then drag it along the pins in one go. What usually happens is excess solder gets dragged off the pins.

The desoldering wick is of very low quality. It should work without any additional flux.
The tip is oxidized and should be cleaned.
This is a mess, don't do it! Get some solder paste.
