@ Perception
your plants look at little nitrogen toxic. See how the end of the leaves curve like that, before even the tip but the curve is illustrative of toxicity.
I would cut your nitrogen by 1/4 or 1/3 in veg and reduce to cut by onset of flowering.
Could also be to wet and just some plants will do that. Mostly though, it normally nitrogen toxicity when this is seen.
Lowering nitrogen will give you tighter/heavier buds, stronger stems and better flowering times.
All that said,
looking good for 7 weeks and I often suffer from same affliction when learning new plants.
Maybe this will help you in understanding some more directions.

An outstanding video talk on natural farming by drake. They are very long but worth it.
@Seamaiden It is an honor! Many years ago I remember you when I came here and you were doing much helping with people. Much respect and keep on keeping on.
What has helped me is understanding this plant in a variety of growing methods and appreciation for growing environment at various levels of the plant from soil/media, internal plant and canopy. Those experiences and lessons have done me well but like I said, I am no one special and am just a pup.
In soils, I use a concentrated sea water mix with regular water. You will want to reduce NPK nutrients by 1/3 to 1/4 (I personally like to learn my plants hungry so I am conservative in my numbers for safety). However, the sea water will help the plant meet its mineral needs as the minerals are water soluble and they are also loved by the micro herd. A bit in teas while brewing are great too.
I also foliar feed it. This is for brix that I do it. A little goes a long way and foliar feeding often is not good.
Their is a trade off in high brix and yield. I like around a 12 to 15 brix level as this is said to be when the plants are too sappy for most above ground pests.
Brix also affects
terpenes and over all health. I consider after brix level 12-15 subjective towards each grower.
I am glad to have assisted.
