can i get some advice please 🙏 it's my first real venture into propagating (i've successfully propped a pilea so far) and i'm trying to prop my rubber plant and my string of hearts for my rubber plant, ive seen no progress whatsoever in over 2 weeks and there are these white spots (are they roots? it is an infection? i have 0 idea) for my string of hearts, do they develop secondary roots or is this how they grow? i've been propping this one for about a month now and this is the progress any advice would be very much appreciated as i'm new to this and not sure if it doing it all right 😅 both are under grow lights and in an ikea cabinet
