I think the plant is in flowering stage. I am first grower so I don’t know if this can be called flowering stage but I think yes. The ends of the leafs are again bad looking
The claw is usually caused by either nute burn or overwatering, I would stick to your watering schedule but lower the nutes slightly and see if that helps, it happened on my first grow and it was because of nutes, what feed measurements are you going? Is it just biobizz grow that you are using?? 😁 also you will know when the plants is flowering as you should see some white pistols appearing out at the bud sites, hope this helps! Keep it lit
they look not too bad...
what soil do you use? and how strong is your grow light?
looks like a bit of nute burn and overwatering to me, but I am a newbie too, so I may be wrong...
