You need to break up your workout too and give yourself enough time to recover in the areas you've worked out. If you're doing the same workout every time you go to the gym and are working out every 2 days it's no wonder you're going nowhere fast.
- Eat more
- Review your routine
- Change up your exercises (WTF would you do 135x5 followed by 275x8 on DL???)
- Ensure you have 2-3 days recovery time between hitting the same body part(s)
Do that, you'll start gaining again. Don't, and you won't.
