Very nice! Are these autos? Im hoping so… im old so Id have to re read the entire thread . As you can see, in the photo, the right hand plant is phototroping, that is bending to the most intense light source. Ideally, the sun travels from East to West and the plant would track its movement. Because your light source is narrow and stationary the plant will be bent there. If your budget can afford it I highly suggest a better light source. While a good light will set you back 350 bucks the difference in pmant growth is astonishing . @dbrn32 is the guru of artificial light and I highly recommend you speak with him in this matter. A better light will also give wider coverage. Those cob style lights are normally hung in the correct distance from each other to cover a bigger area. So in groups… also cobs used in pro grows are hung pretty high and are very strong lights. Im personally not a huge fan of the cob form factor due to the small footprint and diminishing light energy off the sides. The newer panels do a much better job covering wider areas at pretty low wattage. Here is a light that I use as an example of form factor of a modern light fixture
while this light is not a 350 dollar fixture and is too big for you purposes it illustrates a wide coverage form factor. Plants tend to grow straight up and bushy because of great light penetration. Light can enter the canopy from multiple angles, and with your light this is not possible.
As you can also see in your photo, there is shadows on the soil and your plants arent even bushy yet, you wont see that with a better panel style fixture until the plant is thick!
