Beginner Gardening: Lavender leaves dying at the tips, 1 by WonderWeasel

Hello--

I have a lavandula vera plant that I started from seed about May of last year. The plant was started indoors in an 8 oz. plastic cup. When it grew large enough to tolerate the hotter temps, I transplanted it into a 2-quart pot using a mix of 2 parts Miracle-Gro Organic Choice potting soil and 1 part perlite, and slowly acclimated it to the outdoors. Around the beginning of November, it was brought indoors, and (since my pepper plants are taking all of my window space) I put it under a 26-watt cool white "daylight" compact fluorescent bulb. The first two months the plant seemed to thrive, quickly growing new, bushy shoots. Over the last week or so, I've begun to notice that the tips on some of the slightly older leaves are starting to brown and die. I know this can be a symptom of overwatering, but I let the soil dry out pretty well between waterings, but not completely (I use a moisture meter with a scale of 1 to 10, and water the plant when the meter is reading around 3 about 2" from the surface.) I have included a picture of some of the affected leaves. Any and all help is appreciated!
