The link below is where I found the powder mildew remedy. It has all possible signs of powder mildew. It's a white fine powder and it stinks like cheese. It was on one plant in the same enclosure and now it's on this one. The other plant had died but I left it in the room hoping it would recover for a while. No such luck. It dried off and then died soon after. When I did the autopsy, the roots were dry and flimsy looking but still white so definitely no root rot that time. On that one I tried a variation of this remedy but without the oil and soap and I did it while the light was shining on it so that might have led to it drying out, and dying.

The hydro method is a bucket with an air pump with hydroton clay pebbles as the medium. I changed the solution too because it was about time and I just wanted to make sure everything is clean.

I just wish I knew what to do to get past week 2.
