Hello
It looks like a reasonably healthy cola to me. I see how some of the sugar leaves are a bit twisted and curved, and the leaves seem to be a bit dark green with some slight tip burn? I think as you drop down the nutrients in this last 2 weeks you'll see a change in the leaves. And the twist, are they having much wind? If so that can be a good cause for that twisted growth. I don't think it's anything too serious like pests or rot. Just keep giving it TLC, lots of sunshine, a healthy wet/dry cycle, and a few days flush at the end and I'm sure it'll be a very enjoyable bud.✌️ happy trimming.
