    Make sure holders are clean, loaded clean and stay clean. Don't ever put the film emulsion side down on the table when loading.

    Problem solved: it was the pre-soak bath.
    Bypassing it solved the problem

    Presoak is OK with FP4+. 10 minutes presoak is not normal. 1-2 minutes is what's considered normal.

    I must say that I used non-demineralized water for pre-soak, and maybe this is the problem, but since I don't see any benefit doing it, I think I'll just bypass that phase. Now the negatives are totally spot-free.
