Problem with BW slide processing

Been having problems with processing BW slides recently. My chemicals are fresh (Adox scala kit) and I've been following the Adox guide (and watched multiple videos) but I can't get it to work.

First roll: Developed according to guide, got the result i the picture and posted a thread about it. Not enough light/exposure was the only thing mentioned that i could think of (used a 100w ceiling lamp for 2x2 min)

Second roll: Same procedure as roll 1, but I built a light box with a 3000 lumen LED bulb just to try the theory that it wasn't enough light getting to the film (4x4 min). This roll turned out slightly worse than roll 1.

What am I doing wrong here?
