well this is my first grow.
my seedlings have just sprouted ( second set of serrated leafs have yet to grow ) . they are currently in rock wool which is in hydroton media for a DWC bubbler setup.
here are a few questions if anyone can help

when should i add the nutes to the water?

Not until a week or so has passed. The seed had the nutrients the plant needed to get started.

should i add a fish tank heater to keep the water warm? ( its not freezing but its not warm either )

Well, what is the water temperature now? 65 degrees, which ain't warm, will hold more oxygen than 70 degrees. If you do add one, I have to in the winter here, get one that has a control. Set it low and check your temp with a thermometer until its 60-65 degrees. Or buy one with a thermostat. I haven't looked for one of those but I'm sure they are available and expensive.

should i spray them with anything? ( water? thrive alive by technaflora ) ?

You can mist them, they will like it. Its kinda like rain, gets the dust off, helps keep the stomata clean, etc. Some use additives. I use Dark Energy. It only takes 1/2 tsp (2.5mil's) per gallon of water. I have seen thrive alive recommended.

or should i keep my hands off of them and let them be?

You should keep your hands off of them but not your eyes. They will let you know how they are doing.

how often should i water them? ( untill thier roots hit the water )

Yes. Rockwool has good moisture retention, hydrotron doesn't. You do want the roots to go looking for water and I haven't done a dwc grow so I'll let someone that has answer this one.
these are just random bag seeds so well see what happens!
