Water on leaves. In one picture leaves are soaked. Light is magnified by water drops and then cools leaves in spots it sits.

It could be from nutrients touching the leaves when fed.

Look like nutrients have spilled on your leaves, causing a burn.

Lemon Ice 2.0 - Browning leaves Weird Growth
Anyone got an idea what may have caused the weird looking lemon ice to grow like that? I'm guessing a fungal infection or mold, which is weird tho cuz all of them got the same exact feed, time in the plugs etc. Basically its odd because it only affected one (thank fuck), ideas?

I’m seeing brown on the lower leaves. They also appear particularly shiny like a magnolia leaf. Is this too much iron or magnesium?

Leaf discoloration. 5 weeks old
I transplanted these girls 2 days ago and have started them on a new nutrition. I’ve noticed some discoloration on one of the leaves today almost sure it’s the nutrients. Can someone help me figure the best thing to feed my plants? Thank you (nutrition diagram on my first diary)

Hello fellow experienced growers, is what I see on this leaf, combined with a reddening of leaf and main stems really signs of a CalMag deficency? Or do I have another problem? And is 1 ml CalMag Agent enough to counter it? Dont wanna risk anything so close to the goal...

Brown spots on the leaves
Hello, everyone. After replanting, this appeared on some of my flowers. I think it's probably stress after replanting, but I'd rather ask you more experienced ones. Thank you in advance for the advice 🙂

Why are there soon many brown spots all of a sudden in WK 7?
I'm entering Wk 7 and the same lady is hurting again. She's been feeding heavy for last few weeks and doing great. So, I gave a light water/microbes dose w/can and Epson. Now I think its potassium or something else entirely... Brown spotting, yellow, crispy? Thoughts?

Brown spots new leaves - flowering
Brown spots on the canopy and leaves are less greener. I suspect it is Calcium deficiency caused by a acid Ph (my Ph meter was not calibrated). I have flushed it and fed it normally 5 days after the first signals. Is it really Calcium def or another thing I'm missing?

Light burn, light burn due to humidifier water lights?
What do you think caused this brown color on that leaf? I have 5 leaves like that, all the others are ok. I believe it's due to pulverizing water and droplets acting as magnifiers for the light, causing small burns. Also, since they are burnt, should I just cut them out?
