Hello, I've been squatting for 8 months. I've made some good progress, before I would only work legs with machines. Lately, I feel that my progress has stalled quite a bit.

My legs program is the following :
Tuesday :
- Squat 4x6

- RDL 3x8
- Leg press 3x8

Friday :

- Squat 4x3
- Pause Squat 3x5
- Bulgarian Split Squtat 3x8
- Leg extension 3x8

- Leg curl 3x8

I run this program for 6 weeks then I take a deload and run it again.

I feel like I can't add more weight here and I want some advice on what I can improve please.
I weigh 78kg (172lbs), am 1.83m (6'0") and here I lift 102.5kg (225lbs)
