Thanks for your responce guys. She was about three weeks along flowering.
I didn't take pics before I decided to end it all. It was pretty badly effected and I'm stuffed how I missed picking it up earlier, but, I learnt something.
I noticed something amiss a few weeks back but, not having come across Red Spider Mice before, I was not as alert as I could have been and failed to recognise the signs. Shame on me. We learn as we grow, I guess.
Thank you again for always being ready to advise
