That is a nice healthy looking plant. I can't see any signs of a nutrient deficiency or a excess.
Let's see, put more soil, or whatever your grow medium is, in the pot. Bring the soil level up so it is only about 1 inch below the rim of the bag. The plant will still be the same height but will sit a bit higher than the rim of the pot giving more room to get underneath. There is a wrinkle in the side of the pot which is usually an indication that not enough soil was used nor was it tamped down. There could be an area of loose soil there. Sometimes it is OK and sometimes the soil in that area is loose enough that it will not soak up water properly.
Pour less water at a time and let it soak into the soil. Come back a half hour or an hour later and give it some more. That gives the soil more time to absorb water and can avoid dry areas. But, so far the plant does not look like it has any watering related problems.
To get to the back use a small watering can with a long spout. That will help pinpoint the area where you want the water to go since the spout will reach the back.
Looking good and it does not seem like the plant was growing slow. If that is just one plant in that cloth pot I have to ask if you topped it somewhere along the way to create more growing tips.
As
@Phytoplankton mentions leave the plant in a vegetating stage for awhile longer. Then when ready to change the light schedule think about removing some of the lowest leaves to open it up a bit under the canopy. Just remove the bare minimum needed to be able to get the water where you want. No advantage to removing too many leaves.
You could consider skipping the net next time. If those new plants are short and bushy the net might not accomplish much anyway.
If you do want to use the net then figure out a way to use a smaller piece and anchor each piece to one pot. That way if you have to move the pot to get to the back then the net moves along with it.
None the less, just some things to think about while your current plants are going into flowering. And yes, what you have there right now is nice and healthy looking.
