The white trunk is likely just mineral buildup; it happens with hard water. If it rinses off easily, you're fine. (If not, it might be powdery mildew; check the roots for rot/overwatering.) The leaf issue is usually a scorching issue with junipers; they can easily get too hot or sunburn if thier light is too direct. Misting the leaves can help cool it down for first aid if it overheats, but in either case, move it to a shadier spot to prevent further damage
