The plants are definitely happy and healthy! One more suggestion I have would be to trim some of the undergrowth close to the soil so airflow is kept moving through there. This will help fight any possibilities of mold and mildew. Also, don’t be scared to snap off and trim fan leaves as well. You’ll find everything you take off will grow back 5x. I trim mine down to bare bones before flowering to 1) help with light penetration and 2) to guide the growth of the plant whether it be by topping (cutting the center top growth) or lower branching (to help them focus on upper branches development and growth towards the light)
just use the growth you see right now as a road map, as they flower and mature all those branches will grow 2-5x their size now so whatever you don’t trim off, look at the growth now and expect it to be the main big branches. Focus on the branching and growth you want to see grow and think about which stuff will get the most light as they stretch and flower.
Keep up the good work and seriously don’t be scarred to chop off growth you think may crowd or cause problems. Whether if it’s not gonna get enough light, or just bush up too much and be a spot where mold can grow.
Again, Solid first grow!
