In my opinion it looks a bit overwaterd. If you have spots on your leaves its from the water droplets burning them. When water droplets are present on the leaves during sun basking they act as magnifying glasses and burn your leaves. Also, if the tips are turning brown its one of two things, it could be some of the fan leaves startin to die because of flowering or, it may be gettin burned from your fertz. Try cutting down on the water and fertz for a week or so and see how it does. It looks pretty healthy though.

Bugs are always a big problem. No matter how severe it is now, it will get worse later. Get rid of them ASAP. I cant tell you how because i dont know what kind of bugs they are. Post some better pics of some of the damaged parts and maybe we can help ya.

This is just my opinion on what i THINK it could be, i could be wrong and i could be right, who knows....

PS- When you take pictures make sure you get a good clear shot. That picture isnt very clear so its hard to tell much of anything.
