Looking very good NormaJean!
Now, don't take this advice... I'm just rambling and I'm probably wrong...
The lushness of your leaves is intense. That kind of deep, dark, green can sometimes be an indicator of an underlying issue. The cold weather of autumn causes phosphorus to be locked out which causes the leaves to change color. Mix a little standard green with a little violet and you get a very dark, deep, lush green color.
So, what I'm trying to say is that you should keep your eyes open for is a little nitrogen excess and phosphorus deficiency. An imbalance of these element's ratio could be nitpicking, but it might make a difference in the final harvest. The deep green color could be an indicator that these elements are not in the proper balance.
Then again, it could be the lighting, or the camera, or just the particular strain. So take that advice with a grain of salt. You should be increasing the phosphorus anyway in about a week, and dialing back on the nitrogen in order to keep your EC from skyrocketing and then burning your plants with toxicity. So... Either way, a little less N, a little more P, maybe sooner than later.
Many growers, myself included, run veg nutes through the 3rd, and even 4th, weeks of flowering. Every plant, every media, and every grow room is going to be different though and you can use this as a learning experience mostly. Don't change anything yet (if it ain't broken...) just ride this pony for a while and keep your eyes peeled for any leaf curl (eagle claw) or an even deeper darkening of the leaves to the point they are practically blue.
To give you an idea of what I'm talking about:
Can you see how the larger, outer most, leaves on this plant are practically blue? This is an indication of an imbalance of N
in the ratio. This plant needed more P, less N, than the counterpart Blue Mystics beside it. Just another proof that one plant is not every plant and there is no "way" to do things. Your way is the best way, so just keep educating yourself, and then ask here before you apply that knowledge. Ask first and shoot later.
