Is that mold on the subfloor and if so what do you recommend needs to be done?

So i bought this house and wanted to change the floors when i ripped out half the floor i noticed the subfloor was grayish and had some old dark spots. I want to know if its mold or just some dirt from previous flooring https://preview.redd.it/o5zrv5kdud4f1.jpg?width=4000&format=pjpg&auto=webp&s=e646505f86a16b79847593f6658b7c05a0e75a72 https://preview.redd.it/9nqngbkdud4f1.jpg?width=1848&format=pjpg&auto=webp&s=e6e16e23b5ddab44edc6101db1423f1acf4c8350 submitted by /u/Traditional_Law_7904 [link] [comments]
