Looking good so far.
It looks like you're only watering around the plant, and not the edges of the pot. That's not good, but go and sin no more and your plant won't suffer.
Roots grow towards moisture. They will not grow toward dry soil -- they will completely ignore the dry soil near the outside of your pot. The way to water is to get all the soil wet, let the pot drain, then don't water again until the pot feels light and you don't feel moisture when you stick your finger in there about an inch.
The issue with most non-houseplant plants (and cannabis is not a houseplant, even when it's in your house) is that their roots need plenty of oxygen as well as water. In soil, water and oxygen share the same space -- the "empty space" or pores between soil particles. When they're filled with water, the roots could have difficulty getting oxygen.
This is not a problem in the short term. After you water and the soil is wet, the roots can do without a lot of oxygen for a couple of days or so. As the soil dries, plenty of oxygen will get to the roots. It IS a problem if a grower keeps the soil moist by watering every two or three days. Then you'll see over watering symptoms on lower leaves.
