Hi guys! My squash plant seems to be dying, but I can tell part of it is still trying to grow. I'm not sure if it's because of the colder weather (it has gotten to 40's and 50's a few nights) or another reason. There are these tiny dark dots that started forming on them. Does anyone know what these are? Also, should I take all the squash off of it now rather than seeing if it will grow more? Thank you!
