When you're just beginning, you might try out a few things until a way works for you that returns 100% germination (at least once) -- a repeatable process. Although I know it seems like you should be doing something, most of the credit for germination goes to the genetics.
With good genetics in rockwool, you might soak them awhile in water with a few ml of pH down for a little phosphate, but you wrote that you added nutrients -- if so, expect scorched earth. Seeds come with their own nutes. You might still feel like you have to do something to expedite the process. You really don't, but if it works and you're comfortable with it, it's your repeatable process. I've had success soaking seeds in a Ziploc bag for like 12 hrs in a drawer; and then ~12 hours on a paper towel, in a Ziploc bag, in a drawer. By this point, there's probably the slightest beginning of a tail.
And then, you might plant them in 3 or 4" starter blocks soaked in water with a few ml off pH down (the bottle probably suggests ~5 ml/gallon). They blocks are probably pretty good on water for a few days. You probably don't want to spray or mist them again until they've fully popped their heads up. When they've fully popped their heads up, you might give them a light mist above their heads -- but really, you'e just preventing them from drying out until they have roots. Once you get good at that, you might increase watts to about 120 and see how much more robust roots are versus ~40 watts, which would just keep them alive and growing slowly, but probably not thriving with thick, fuzzy white roots.
If you have 10 seeds, run 2 or 3 to start; see how you do; reassess if they die, and remove yourself from the process a little more each "next time" until you have 100% germination. Then, you've found a process that you can be comfortable with.
You might need more seeds.
