    The usual questions Bro'
    Are you checking the pH and do you have air flow in the grow area?

    How often are you watering this plant? What size container is it in?

    I can't remember the name of the acid in vinegar but I read somewhere that it isn't great at maintaining the pH. Get some pH down(phosphoric acid) from a grow store or ebay. As for the fan you need to extract the spent air about every 5 mins, work out the volume of your grow space and compare that to the flow rating on your fan, and remember that things like ducting and carbon filters all reduce a fans capacity...
