hello there!

this is my first post on this forum! wooho!
anyway, i'm kinda beginner in home developing, and until now I developed 120 T-max 100,
today I developed a film I got with my holga a friend bought me. it's Fuji neopan 400 and I used ilford chemistry like used on the T-max to process it, of course used the digitaltruth database. but as I took it out of the fixer I saw the film is gray (well most of the photos are overexposed but well, it's holga) and it's actually a layer still covering the film.... maybe it wasn't enough time in the developer? is anybody here can understand what i'm talking about?....

thanks for any help!
