Plant prob. Is it underwatering?

Ok my plant has been doing very well till today. Well I am usually around it everyday. Well I left my plant alone for 2 days for my brother's wedding in Napa, CA. Anyways, I checked it this morning to find about 4-5 fan leaves that are brown on the tips and the top growth is not coming in as strong as usual. The ground looked really dry so I assume its that, but calling on experts to verify or debunk my theory... Thanks...

pics.........good ones.

if you gave it a good watering before you left. i doubt she would have dried out in 2 days.
check your ph.

any ideas?

You've got a few insect marks on the leaves that u need to see to.
