White Widow Auto

First grow ever. Seed was planted on 19/12. 1inch deep into the soil. Soil I'm using is the Bio-Bizz AllMix. I'm watering with tap water but I live in a mountain area so water is clear and healthy. That being said, I still let it rest some days in mason jars before using it. I water when I feel pot is getting lighter and I see top layer of soil is dry. I tend to water without runoff. Light is currently at 23" or 60cm from the seeds. 20% intensity.
