Nutrients

What strength nutrients and what nutrients should be used for clones coming from a EZ Clone machine being put in rock wool?

are you putting the clone in soil or are you in hydroponics?

this ones easy.

almost none, less than 1/4 strength at most.

depends on what line you are using and if its nuted soil or not or will it be hydro.
Some of the cheapest nutes are GH # part series. 1.25mL to the gallon of each part for rooted clones

They'll be hydro, not soil

nothing for a week, give it time to settle in, then 1/2 str fert then full str,

Tap water or best is reverse osmosis water and keep it between 80-85 degrees.
