Q.Soil
The soil of my aloe vera has turned white a week after I gave it water. Will that damage my plant?
Inspect the soil to help determine if it is mold, perhaps from excess water in the soil.
Crusty white residue could be build up of salts; this could come from over fertilizing or watering with conditioned water.
Make sure the soil is well draining. Aloe soil should dry between waterings.
Try using distilled water or leave the water from you tap to set on the counter for 48 hours before using.
If it is excess salts you can try flushing the soil, but you will need to avoid overwatering.
You could also repot the plant with fresh potting mix. A Cactus soil mix is appropriate.
I'm listing a few links for you to help you.
