too cold in room...need temps in the 80's for propagation.

water temps as stated above 68-70.

Do you know how to take cuttings? If you didn't leave a node, your chances for success diminish.

You never add nutes to cuttings or seedlings. No roots=no uptake, so you are just burning them.

The only 2 things I would ever add to cloning solution (water) is superthrive, or Liquid Karma, or 3-part bloom (for phosphates), but I don't generally. Phosphates help the plant to root.
