Can i spray my clone with Rapid root Start or should i spray with plain ph water?
This is my first time cloning
First off a clone has roots, a cutting doesn't.
You say clone so it has roots.
You can feed with your rooting solution for like a week or so after she shows roots.
Your rooting solution has some food in it for the new clone.
after about a week, I transplant in soil, you usually will have enough nutrients in the soil to last @3 weeks. after that start feeding with nutrients.
If your hydro you can start following your feeding schedule when you transplant.
IMO- I wouldn't foliar rooting solution. even if it says you can on the bottle.
Good Luck on Your Grow
