I have been growing a baby wisteria so far indoors. Eventually, when it's big enough to withstand weather conditions, I hope to plant it outside. Currently though, I have noted white splotches on the leaves. What could be the cause and how do I address the situation?

If they are chalky, it could be the type of water your are using. It may be mineral deposits building up. Watering with a distilled water will stop this.
