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.

Plants get weak spots in cell walls. Nothing to worry about

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

Ilness or deficency?
Hello I have noticed some lack of green and brown marks on some leaves. They are all from one plant and mid-low distance from light. You think its nutrient deficency or some ilness? I have noticed that the coco was really dry so i opened a bit more the irrigator.

Is this more nutrient deficiency?
I believe the yellowing and brown spots came from the roots starting to suck up more water than the previous weeks. Do you agree that the Durban Poison had some nutrient deficiencies?

Potential bud rot?
My critical cure has some of the smaller leaves near and in the buds which are starting to turn rusty brown. Is this a starting sign of bud rot? Should I cut them early? I do not see anything abnormal under the microscope or when separating the large buds by hand. Thanks!

Deficiency?
Anyone seen leaf damage like this before? 6 weeks into veg in FFOF. A few fungus gnats but no real infestation. Not adding any nutes yet. Really concerned as the plant is looking less green and more yellowy than it did last week.

Brown spots on leaves
What seems to be the problem with my plant? The old leaves get brown spots whereas the newer ones have yellow edges. Is it a pH issue? Is there a fix to this? I grow in soil and the plant is 4-5 weeks old. Thanks for help!

Is this a deficiency or light burn
Hi all my other plants are perfectly fine except for this one it has brown edges on the leaves and has been growing the slowest out of all my plants and I was just wondering how I could fix this? I checked the run off PPM yesterday and it was 1100 so I flushed it and now its 700

Are those nutrient defficiencies? Which ones?
A plant had interveinal chlorosis on new leaves and then proceeded to show brown patches between veins on middle leaves. Another has coppery brown spots on leaf edges on the middle of the plant. Both were rootbound in living soil (peat/perlite/hummus + ammendments).
