Took clones out of propagation around a week ago, past few days have noticed leaves curling around the edge’s (canoeing) I’m thinking environment as have been struggling with the cold some days I was checking it was sitting at 17c at lights on now have temps at 22c

they generally canoe when temps are too high, but temps are low which seems to contradict this. Are you using a heat  mat for the roots?

if not id get those temps up to nearer 26/27

Try getting temps a little higher and you should be ok
