I sprayed again on Friday (most plants, not just affected ones) and am planning on doing it again on Wednesday. The main affected plant I cut back reasonably heavy, and it's not looking great but it's still alive. Actually has some clean regrowth that isnt affected (yet). Some shots below. The ones on either side of it are looking generally ok, but like I said, rehosing every couple of days.
I thought the sulfur was meant to work...you got any other ideas?
Good luck mate, these little sods make aphids look like nothing.
Just keep at it. and mix your lime sulphur strong. 25ml - 50ml + per L of water depending on how keen you are. Hard to tell from above pic but looks like things may be coming right?
