HELP Jade dying, Leaves turning yellow, green ones falling off.
History, I moved my 4yr old jade plant outside for a few weeks and it was doing just fine. I sprayed it with some organocide to kill off some bugs I saw on it. My mother / sister over watered it while I was gone for one week. Most of the lower leaves are starting to turn yellow and the upper newer green leaves have started falling off at a very rapid rate, about 15 in the past 3 days.
I have since moved the plant back inside.
I re-potted my jade and inspected it for root rot and found nothing. The leaves feel kinda gritty and sticky unlike my other ones. Do any of you have any suggestions?!?
