Yes those are pre flowers. Clawing leaves can be a number of things. Does not look to green to me. How often are you feeding.What are those NPK's? What are the temps? Humidity? Lighting? All these can be a factor. Actually here check this out. https://www.rollitup.org/marijuana-plant-problems/150004-plant-moisture-stress-symptoms-solutions.html Read through it there is some great info that will benefit you. Hope it helps. Good luck
looks like it has both preflowers and forming budsites already. Leaves look dark green, do not increase N, but so far no foxtailing of cupping, I wouldn't say you have a N toxicity. Go ahead take a chair, popcorns and watch it growing!
Peace
So i had her out in the sun today and thought i would do a top down shot on natural light do you think the leaf is darker than it should be ? most of the bigger leaves are this colour the smaller leaves and new leaves are not as dark.
