Even putting a plant under 12/12 for two days before returning to veg has been hit and miss- mostly miss.

This almost always works for me, I usually do it in solo cups.

I recall seeing someone post about flipping to 12/12 for a day or 2 in veg to get preflowers. Just need to know how to work that.
