A lot of the leaves that have those black marks on them are turning yellow now, its hard for me to tell if the problem is still rapidly spreading, it seemed to slow down if so, but i hate the looks of the two girls, look so sick

if its a toxicity should i jsut flush today? i've never flushed so it makes me me a lil nervous and i'll have to look up exactly what to do when i flush and afterwords
PatSajak Reviewed by PatSajak on . Sick plants, black leaves curlinng etc, overwater? I cant' figure out what the problem is, I've got 5 plants I just switched to flowering about 2 weeks ago, 3 are looking great and budding nicely, 1 has been dieing and not budding, and the other one is on that same path, spreading these Black marks all over the leaves, and then they turn yellow and curl up and are cruncy/die and i have to pull them off.. It spreads from the bottom leaves and gets all the way to the top leaves, only the newest growths are green, but the 2nd to newest growths are Rating: 5
