My plants were doing fine, in fact great. But now all of a sudden, they are all dying. The leaves are drooping and getting brown and black. few examples:
The temp soared to 45c degree here but they were kept in bright indirect light and with a huge tub full of water near the plants for humidity. I have no idea what happened to the plants all of a sudden. Song of Indian, Rubber plant, Monstera, Arrowhead vine, Poinsettia, dumbcane and all. What could be wrong here? I checked roots of some plants, and they are no signs of root rot.
My watering technique is same as before.
EDIT: More pics
Funny thing is that my Lemon Lime dracaena is super fine and growing along with Croton plant. But all other plants are dying.
