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

Just to confirm, this looks like nute burn, doesn't it?
Burnt edges, tips curled up, canoeing. I've been having trouble balancing airflow and heat in such a small tent, and as a result the tent is on average about 28 degrees celcius daytime and the plants still get a lot of wind. Looking for whatever advice you can give! :)

Normal or should I be careful?🤔
First time I see these little dots on the leaves, can anyone identify them or is it nothing to worry about, as I'm thinking? 🧐🤔

Leaf changed color and spotting, help!
Any idea what I need to do to fix this? I think I over fed and then I recently did and RO flush. Then I fed it calcium herkley and harvest recharge in a little general organics bloom.

On lower leafs some brown patches started to appear and leafs are turning to a yellow color. Think is either Cal def by how it looks like or it is because of PH fluctuations as last week we changed our PH to 6.2 for 4-5 days and now it is back to 5.9 and under 24h spots appeared?

What should I add/subtract/do?
Can anyone help me figure out what is going on? THC Bomb auto is 23 days old and starting to exhibit some discoloration. Indoor grow, in ProMix with Fox Farm nutes. What should I add/subtract? This one is going to be a monster and I don't want to screw things up! Thanks!

What issue is this?
I have some dark spots on a few leaves, some looks like a cal or mag def but some are a little hard to identify. What do you think these are? These haven't had nutes, about 25 days old or so, Nectar of the gods #8 fed PH 6.3.-6.5.

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.

Plants deteriorating rapidly, pls help
Plants not looking good! Help! White tips at the end. Brown patches. Leaves curling. I've been feeding it 0.5L Advanced Nutrients Coco Big Buds. The light was fairly close, at 30cm. I've raised the lights to 60cm. It was also very humid, so I've opened the air vents .

Hello GD friends. My little Diesel Automatic is showing some odd mosaic'esque coloring on the baby leaves. I'm inclined to just let it go for now and see what happens. But if there are any suggestions on helping her out, please let me know! Thanks!

Hi 8th week of flower. Bottom leaves have turned yellow and died and yellowing is rapidly moving upwards. I think it's nitrogen deficiency so I've added more Biobizz Grow. Would be good to get an expert opinion! Thanks

I'm still guessing what caused the disease i noticed on a single plant the first weeks of grow. A disease that didn't spreaded at all, and that affected only 2 leaves. You can see it on (Week 2 - Photo 21), (Week 3 - Photos 7, 11 & 17) & (Week 4 - Photo 4).

I'd like to know what happened to my plant but I'm unsure how to properly describe it. The photos in my diary should be able to make it more clean (W18). Maybe it was botrytis but I caught it on time? Or maybe something else? The trichomes got dark orange where all this happened!
