i dont think it is because of high temperatures since it is affecting the bottom leafs only, anyways how high is the temp? how old are the plants? and yea pics would helpis this duh to heat stress maybe? its been exposed to high temperatures for a short amount of time multiple times. i will get a picture if you need it...
wow seriously guys... look up.i think it might have too much water.
Leave were creating shade so the leaves underneath didnt have enough light, watering was wrong, too little I think. And I started using h2o2.what was the problem tho?
Yeah, that and making sure everything else was perfect. It is just a very picky plant and needs constant attention more so than my other plant. =/so you trimed it down a little ??
