    Try a good magnesium sulfate soak. About one tablespoon of epsom salts per gallon.

    Looks like severe dehydration. Soaking in kelp or even mild glucose solution would help.

    Agree with Sriram completely. They'll dry out a lot faster under lights and you'll have to raise your humidity as well. Need to plump those roots up again. Regarding the white flecks, check under the leaves and around the leaf axles for mealy or scale just to be sure.

    The leaves also look mottled. Magnesium is necessary for photosynthesis and cell wall structure. On top of looking dehydrated the leaves are not a uniform green. The older leaves will be affected worse and the newer leaves will look better because the plant will direct nutrients to the newer leaves. To soak in whatever you decide to use (personally I'd use magnesium) just fill up a container large enough that the pot will sit in and leave it for a few hours or even overnight. Lately I've found with a few rescues which do not have many roots that submerging the whole plant - leaves and all plumps them up nicely, but mine are bare root so I can see what is going on with the roots and it is easy to submerge or soak the roots.

    Concur with Karin, fill in a large container with good quality water (RO/Rain) and add 2ml of kelp to a Liter or a teaspoon of glucose or 2mg of Magnesium sulphate and stir well. If the water is slightly warmer it could be better. Soak the plant in this solution for 15-20 minutes or even overnight.

    Good question, sugar that we consume commonly is sucrose I suppose?

    If dehydration is the problem, by rehydration the younger leaf normally will recover and become plump again but old leaves will leave some wrinkles.

    Corn syrup can be used for glucose
