yes put your plant in the bath tub and run as much water through it as you can, let it sit and do it again. i had a problem last night, not that yellow but certainly the same thing. crispy brittle leaves, drooping? i made the fert 20-20-20 at the right strength a couple of days ago, but ignored how much to use in a pot, put more than twice the amount of fert water i needed. the plant was frying, this morning it was looking its same old self again. damn i need to get an ac adapter for my camera, i could show you the difference.
