Hibiscus: Having some hibiscus issues, help?, 1 by AmandaTaylor7

Ok, I'm not doing something right, can someone help me? My leaves are turning silvery in the middle on different potted hibiscus in my backyard. The ones in the ground are not showing this problem, so I don't know if that helps or not. Also, one thing to note is that they get a fertilizer with the lower middle number each week (no more than 1x a week) and they were treated with Ortho Big-B-Gone about a week and a half ago due to a whitefly problem I found. Will this silvery leaf thing go away? Is there something I need to do for these babies?
