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.

Help diagnose hydroponic plants! Too much light/heat? Nutrient issue?
The plant's leaves on the right are wilting and drying out, while the leaves on the left are spiking. Just did a nutrient/water change but it didn't help, and it looks like growth is being stunted on the right plant. Humidity has been around 45-55 rh and temp 70-80F

Browning on the leaves?
I am worried about the leaf colour I feel like it’s slightly browned on the tips. Interested on what others that know what they’re looking at more than me think. Good chance I’m being over protective. I appreciate you.

Ugly leaves
So, guys.. I asked a question here, like 3 days ago, about some leaves. I think I have found out what has happened. Mold ignition, but very few, at the root. Have already medicated. Do you think this is a mold symtomn? Cheers!

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...

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?
