New here

Hey I was working with a few singing programs for last about 3 years...I was struggling quite a bit and basicly still I am.I was doing scales from the begging so I get a few bad habbits because I was doing things incorectly and also I have problem with a weight I guess.Then I started few months ago just speak easy sounds without scales and my main point was feel free.Then I was humming and I find it more easier if I ad kind of buzzing behind the soft palate and into the nose.
Is this the right sound production or I will get bad habits by doing this?please need some opinion
