Garden Pests and Diseases: Is this a strawberry disease?, 3 by milknsky

I bought about 2 months ago a strawberry plant in homedepot and it looked fine and was giving small red strawberries a little sour though. But recently I noticed that some of the leaves were turning red on the outside of the leaves. I got worried. Is this Normal or is it a disease. Is it treatable or do I have to get rid of it? When I first bought it I made a mistake of watering it with water that had liquid fertilizer that was meant for another plant and not sure if it burned the leaves as it did to another plant because the fertilizer is not supposed to touch the leaves. So I'm not sure if its that or if its an actual disease. Please help, I'm a total newbie in gardening.
