hello, you can use plant yo-yos or any kind of string with a paper clip to pull up colas from above, you can also use stacks but its a little late in flower to damage roots, at first glance the problem seems to be overfeeding, too much nitrogen causes that dark green and clawed leaves, too much potassium or phosphorous can burn the leaves just like those brown leaves you got, i think you just have to dial down the amount of nutrients my friend
