Don’t know which one is which & plant looking really weird

Hello, i have planted five different strains:

auto mimosa punch - advanced seeds auto sour diesel - fast buds auto Amnesia Zkittlez - fast buds auto Pineapple Express - G13 Labs auto Think Different - Dutch Passion

Due to my marking error, i have absolute no idea which one is which. Won’t happen again lol Do you recognize any of them?

Also number 2 looks really weird, is it male or hermed, should i toss it away yesterday or should i just wait it out?

Pretty new grower. Using BioBizz All Mix medium and liquid nutes by their chart. My ph-meter broke so no idea what is my ph.
