or two, lol. I can't keep both off any of these plants. If the watering doesn't help then it's probably more serious. When the plant needs water it points it leaves straight up to funnel moisture to the stem and base of the plant. Only severe dehydration causes the leaves to droop.
cool, thanks for the heads up. I'm not a hydro guy (explains my earlier mindset) so hopefully somebody else can lend if you continue to have a problem. Those roots look healthy to me but maybe slightly tangled.
Check the ph as well unless you do that regularly.
