It looks funky as hell the leafs are hard n dry as hell and it looks kinda like brownish rusty I guess it's the only one of 5 that has a deficiency but the lower leafs are dying on all of them,they are getting nitrogen (what I think is a bit much was to much) will post pics of all later. It's a hassle for me and the pic situation right now but check this out trying to get a better pic will post if necessary
