I have just glanced over a few posts, so excuses any doubling up.
GeneralHydro M .44, G .44, B .44, Epsom .11 per Litre diluted to 1/8th strength.
I fill the hole in 1.5” rockwool with some scraps wool, start new hole to match cutting size.
Pre-soak with ph 5.2, shake out and re-water at ph 6.2, then 6 shakes with hand in bucket
I use a cheap 12 cell Propagation Box, put 3 hole along the top and insert a 1.5” piece of air tube in each.
Then I put Propagation Boxes in temp controlled area at 81-82 F, to pre warm. Or just near a heater with Digital Thermo to watch.
Cutting from middle 1/3 or above, Transition or Bloom nutrient a week before can help with stored energy.
I leave the cutting in a small "Cut down Measuring Tube" full of Clonex. Transfer some in the hole with toothpick before putting the cutting in.
Timing is everything with cuttings, after about 8 days I am sorting those with roots and thinking about the first drink of 1/8th nutrient at ph 5.7 if needed. This is going to vary depending on your technique and equipment. I never spray plants, unless they are very slow to take, where it will also help to wash of toxins.
I do things different to anybody I know, what works for me may not for someone else.
Most important, have fun
