Help Please Mights, Burning and Yellowing

Please help this is my first time grow when its started budding i have it on 12/12 been on that about two week he was tweaking up alot and i have just started feeding coco A and B.I had to move him cos he was in the open i have moved him to a better ventilated space with bright yellow walls with a big fan upside down on him. I looked this morning and noticed the two bits on the tallest stem was burnt and there is a couple of brown spots on some of the leaves i am not sure if should cut them off or not but to make matters worse some of the bottom leaves are really yellow. It still smells nice but I am just worried as I don't want my Maisy to die. Please some one help.

Should i cut the leaves?
Still give Coco A and B?
Any other suggestions would be marvellous thank you once again.
