how much nutrient should I use for my new grow?

[lincon1231]

Im starting a new grow with some auto flower strains.
Sugar black rose, 2 fast 2 vast and auto colorado cookie
now germinating in paper tower
then im gonna put them in solo cups in coco

Im using FoxFarm hydro 3 sets and i also have clonex solution
My question is do i need to add cal-mag at first?
or just some clonex solution for the starting then add cal-mag later?

Do you mean Solo cups and not up-potting? That's a fun stunt, but your plants will be happier in bigger pots!
Look at the FF website for recommended dosing schedule, then start with 1/2 what they recommend. That's always good starting advice.
And yes, you will probably need Ca/Mg with coco--best to dose your coco from the start.
Good luck and have fun.

Im gonna add cal-mag and clonex solution once they germinated, use FF nutrient in haft doze after they get 3 sets of leaves
How's that sound?

I don't know anything about clonex. I'll bet you can run half-strength FF for the entire grow. Seriously, manufacturer's recommendations are always on the high side. FWIW, I dose nutes twice, so running about 25% strength works for me.
