Identify the issue...and how do I correct it

Leaning towards too much fertilizer which is burning the plant, indicated by the very dark leaves... some phenotypes are just more finicky than others but id cut back the nutes by about half

There is nothing wrong. Most likely you got water on that leaf while watering and the droplets act like a magnifying glass. I have a strong light and it will burn a leaf if there are droplets left. Also that looks more like just a dead leaf at the bottom. If it was say nitrogen burn every leaf tip would have it. Not just one. Unless you see it on multiple leaves I wouldn't sweat it too much my friend.

Dark dots in leaves. Lamp burns?I saw this dark dots in leaves but only she has it. She was exactly under spider-farmer sf1000 at 30 cm. Now I moved to other softer light at 40 cm. What do you think? Lamp burns? They're dry and curl up. Some images are edited for better appreciation but you have also originals.

Having an issue where the leaves are spotting Brown. Iโm adding cal-mag and am not having this issue on any other plants except for this one. I thought it could be from misting the air with a spray but stopped that for a while and it is still continuing.Week 3

Bright green spots and wilting.I seem to have some wilting with some bright green spots on some leaves. I just potted up and she's at 20DLI, 0.6 VPD, 790EC @ 6.0pH. 75F, 71%RH, autoflower in canna coco pro plus.I turned my fans down a little since they were a little aggressive, so I'm hoping that's the issue.
