My pelargonium's some leaves are not green any more.They are nearly white.But it is blooming..I am using fertilizer..It is Compo algoflash for all blooming plants..(I used it 2 times..My old fertilizer was Compo Geranium fertilizer.But it is finished.So I bought algoflash) Do you have any information about the problem.Fungus or bugs?
