Here's an odd question. I used some neem oil on some of my hoyas, in particular, the variegated macrophylla and subcalva that I've been having some problems with, just in case it was some sort of mite issue. (I didn't see any, but it doesn't really hurt so I did it as a precaution.) Within a couple days, both started multiple growth nodes. In the case of subcalva, a bunch of rooting nodes as well. Has anyone else noticed anything like this? Is neem oil known to be a growth stimulator, or do you think it is just coincidence?

I did also spray a neem solution on buotii, sp. Tanna Island, and lacunosa, and they are also growing a lot, buotii especially. I've never seen it fill out its leaves so quickly.
