I tried the dishsoap/baking soda/RO water/vegetable oil spray to remedy the white dust and hopefully it will recover but I can't tell if it will help.

Does anyone have any ideas or suggestions?

The PPM is about 200 and Ph is 5.8. I adjust the Ph on a daily basis.

And the humidity in your room is? You will not kill powder mildew or grey mold until you control the humidity. And forget the baking soda , if you to use a bicarb type spray then utilise *potassium* bicarb , it's a bit more efficient than sodium bicarb...........


Look this up....SNS244 , get some. If you still have it after that your next solution will unfortunately be something heavy such as Eagle 20.
Bluenote Reviewed by Bluenote on . Is this mold? My leafs just went droopy and there's some sort of white stuff on them. One of the leafs feels dry. I misted the soil this morning and it feels moist under the top part. Rating: 5
