hi all
I recently acquired some cuttings from Upland Nursery here in SoCal, and they arrived in good shape besides this cutting of Penang Peach....I just started to callus them

What do the plumeria experts think?
Should I re-cut and begin callus process again? the cutting has grayish color all the way up to the tip and is adequate length to take a re-cut

I apologize for the poor picture quality, taken with my phone and the autofocus was going haywire
