I have been looking in the forums for a solution to this issue and have not found a problem yet. Can anyone tell me what is wrong with my plants? I have 3 plants in total. the two largest ones have a condition in the lowest leaves where they are dying and curling down by the margins. Here is the picsthis is the 2nd set that has suffered from this issue. the older sets have been removed. The edges that curled down and paled will soon turn brown and die.
