Any ideas on what's going on with NL-2? Fan leaves are discoloring, interesting pattern. From Websites, I'm thinking a potassium problem, but am not sure. And am not sure how to correct this close to harvest (3 weeks give or take). Thoughts?

Started LST but now plants look a bit sick?
I attempted to do LST but I think I've maybe started too early as some of the leafs started to wilt kinda bad afterwards. Was careful not to break anything. Edges are curling and have discolored. I have a feeling they're a bit short too? Photo from 5 days ago and today.

Nute Burn? Or something else?
I'm seeing a lot of yellowing and dead/curling leaves on my girls. I thought it was nute burn so my last 3 waterings were nute-free, CalMag Only and pH'd. It seems to be getting worse. Could this be something else? Any advice is greatly appreciated

Brownish stains after transplanting
What do you think this is? I have recently transplanted it outdoors. These stains appeared the day after. Might it be sunburn? What can I do if that’s the case?
