Need help please

Hi guys i need some tips on preparing rockwool. I know there's info online i can read (and i have) the problem is i see alot of conflicting information. My seeds have been in a paper towel for about 20 hours now and should be ready in the next day or 2. I need to know the proper way to prepare my rockwool bc these seeds are expensive and i don't want to fuck them up lol. Do i soak them for 24 hours? If so should i add nutes? What ph should my water be? Any and all help is very much appreciated
