Very long mobile sections / Custom mobile home page

Hello,

I notice that the mobile site looks absolutely horrible on iPhone and iPads. I checked on a samsung phone and looked somewhat alright.
On my iPhone 5s i have to scroll forever to get to any text and once i do it’s really off. I thought i’d try turning responsive site off for now but there is some weird line running throughout 3rd of the screen vertically.
My responsive layout is set to 768px and i’ve tried lower numbers with no luck. please help
