Here come the buds now !!!. This part is very enjoyable to watch progress. If you rub the stems now , you may start to get a clue to their finished aroma. amd the stickiness will start to show up too. Now they are in flower properly , you have to watch the moisture levels in the room. Buds can withhold airborne water molecules so can incite budrot if kept hot and humid. There are inexpensive temp gauges with temp and humidity on to keep track too. Ideally we try to start reducing the R.H to a eventual 35% approx if possible. Thisbis more important if you have a lot of plants kicking out moisture too but good airflow can move it well too. Keep the faith your doing ok.
Looking nice and healthy but remember they will double in size when flipped too !!!!. I would consider how they will fit in with the space your using and plan way ahead. Flip those girls and maybe tie them up with some lst to help manage them . they are going to be very tall and need support . stakes may be a good start to try to shape their light coverage .
not sure what nutrients your adding??? but get that under the light at the correct height (check manufacturers instructions) and maybe give some root stimulator - i use canna rhizotonic and basically it reduces stress to the plant and helps grow strong deep roots.
and the main stem could be stretched due to your light being a bit too far away.
But yeah basically keep feeding and get the light height optimum and it should be good! consider switching to 18/6 light schedule coming into flowering
