Help plant got sudden wilt

My ak-48 ( day 23 in flower) went from a robust healthy plant to sudden wilt over night. What causes this and is there any thing I can do to bring her back. I have flushed (24 hrs 7.5ml h202 with 10 ml Flora Kleen/gallon) then drained and refilled with water with tea( 1 cup/gallon.) 24 hrs later the leaves are drying out and falling off. I grow RDWC in 5 gallon bucket with 5 gallon control bucket. Thanks, Cptrips

slimed roots, no oxygen, or no water are about the only things I can think of.

^ what he said. Run the tea and no nutes for 3-4 days then add low nutrient and more tea.

Raise your lights way up, let them heal. Pictures would help

I cant seem to add pics. But good oxygen, water level good as was temp 65 ph 6.0.Roots don't smell bad are a light beige in color.

Is it first time you used flora-kleen?

The other thing I thought of is do you foliar spray? I somehow melted a plant one time after I foliar sprayed it.

Thanks Hydro for the thought. This plant was so healthy I hadn't had to spray for Mites or Mold. No Liquid Light either as I've been fighting mold and I don't know if Liquid light kills or feeds mold.
