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.

Brown spots and yellowing pictured above. My best guess is a Cal/Mag deficiency. Was feeding Botanicare Cal-Mag Plus at 1 ml/l up until ~2 weeks ago (friend has been watering while I was out of town). Before I feed her, any advice on what the problem is and how to correct it?

Tips turning color

I already posted it, but it's better to see here and it continues to spread
This appeared after a strong storm, but it doesn't stop spreading..two guys told me it's from the wind, as I assumed, but with the fact that it's spreading further, I'm worried

What’s causing some of the leaves to look like this? Is it a deficiency or excess? I was watering with 1000 ppm, but I saw some burnt tips and dark green color on the leaves, so I gradually lowered it to 500 ppm, and today I noticed those spots (the drained water is at 750 ppm) (coco and perlite).

Could someone help me to identify the issue my plant has?
This girl isn't looking healthy anymore and I need to figure out why. What I did: I topped her pretty early but she recovered well (you can see it in my grow diary). A week later I transplanted her from 0.5L pot to her final autopot 14L. After that she had a hard time recovering.

Brown/Grey spots on the leaves
Hey, I hope this is my last question for this grow :P I've noticed some brown/grey spots on the yellowing leaves, what could they be, deficiencies or sunburn? I'm still feeding the plant with nutes, but the next watering will be a flush, so I didn't expect discoloring before that

Do I have to worry?
Only on one leaf of one plant. Is this some fungus or virus? It looks a bit like coffee rust, but I couldn't find anything else like it. How should I proceed? Thanks in advance!
