Don't think so or you'd ewe it on more than one leaf. Could be just spillage of nutrients burnt on by magnification of the light

Brown spots followed by necrosis on Mandarin Sunset.Any idea what could be causing this necrosis on my leaves? Starts with the spots and grows to crisp up the leaf.
My soil should have plenty of calcium and magnesium. Happened once before on Gelato and never deciphered it.Week 10

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.2y ago

Need advice as soon as possible. Please see last few pictures of DoSiDos week 3. Am I looking at mottling here? Soil ph maladjusted? Please help if you've seen this before, and what steps do it take moving forward (or am I paranoid, IDK). Thank you!Week 3

Does this look like minor leaf burn, too many nutrients or something else?I believe two of the plants developed minor leaf burn. One has white streaks on the middle and outer portions of several leaves, and the other has a rust, reddish stripe parallel to the center of several leaves. I’ve attached pictures above. Thoughts are greatly appreciated.5y ago

Leaves fading and dying, started from bottom but spreadingI’m starting to be at a loss with this. Calmag issues earlier in veg, seemed to improve for a while but now bottom leaves started to die - I thought this was just due to beginning of flower but it’s getting worse and spreading even to healthier new growth. PH (should be) fine.5y ago
