Push & Legs progressing, but Pull day stalled on bulk – advice?

Hey guys,

I’m currently bulking and my push and legs workouts are progressing well — I’m adding weight or reps almost every session.

But my pull day isn’t progressing the same. Sometimes I can’t increase weight at all and feel stuck.

Pull workout:

• Pull-Ups – 3×8–10
• Close-Grip Lat Pulldown – 3×8–12
• Seated Cable Row – 4×8–12
• DB Preacher Curl – 3×8–12
• Hammer Curl – 3×8–12
• Shrugs – 3×10–15
• Abs – 2 exercises, 3×10–12

Training close to failure, eating in surplus, sleeping kinda ok.

Is this normal? Should I adjust something?

Thanks.
