    It definitely could be the cold, as anything below freezing will start to make it show signs of damage. If this hasn't been the case, then My next guess would be a fungal infection. If it has been very wet lately, then this could be even more possible.

    If you think it is likely the latter, then you can apply wettable sulfur to the soil, and it can help clear it up. If it is cold lately, then you can possibly wrap the tree in burlap on those nights.

    Light and watering are the most likely issues.

    Light: Full sun. Move your sprouted guava to a very sunny place as soon as possible. During summer, move outside to a sunny patio. In the winter, move inside to the brightest location possible.
    Water: Provide regular water during the growing season, and reduce watering during the winter.
    Soil: A rich typical potting mix will do fine. Good drainage is important to protect the roots.
    Fertilizer: Feed with a weak liquid fertilizer throughout the growing season.

    Changing the environment too much at once will cause this. Depending on the power of your lights, and how far away they are, you will want to mimic the sun as much as possible. This will require 200 actual watts or greater. If you have a PAR or Lux meter, this should measure around 300 to 500 PAR or 3000 to 15000 LUX. It sounds like the plant is in shock.

    Another thing to consider is your soil. If the soil has too much nutrients in it, then it will burn up any seedling you put in there. It is necessary to use a light mix for germination.

    Leaching the excess fertilizer with water is less traumatic than re-potting at this point, which would cause some root loss.
    I don't think you need to run water through for an hour or two, just water heavily a time or two and hope it refoliates.
    I'm not familiar with Agloflash and I can't find a list of ingredients, but I prefer a slow release organic fertilizer over concentrated chemisty, no matter what the claims.

    Even then, following the directions for application rate is important, guess-work gets your plants in trouble.

    This appears to be "edema", an environmental and physiological disorder related to water uptake and retention, and not a pest or disease issue.

    Your case is extreme and rather unsightly, but there is no cure needed or available, except as the following article suggests, soil and water management is important.
