Sorry I actually have the flu so my head was a bit groggy, lol.

I'm Starting my seeds in rock wool for my hydroponics system and placing them in a seed starting tray should I add a little nutrient to the water than add it to the
ROck wool or just add water and no nutrients.

If the seeds haven't sprouted yet they don't need any nutrients. It's a waste to use them at this point but wouldn't hurt anything. A couple of days after they sprout I would start using a very diluted nutrient. Something like 10% to 25% of the full strength nutrient solution.

I have not have had the greatest luck with rock wool but when I was I just used straight water till they sprouted. I have found that using agro max starter plugs work great usually have the seeds sprout in about 24-36 hours with a heat mat under the starter container with a high humidity dome.
