My water sprite tips turned brown turned out to be algae. Diatom algae if you rub it off it comes of. I've had other plants go clear on me but new leafs grew out. I hear some will die from shock but it usually grows new ones just cut off the clear ones. I'm new at this also started oct 5 with a 50 gallon and now just set up a 10 gallon. It's all good so far.
