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 dying leaves
What is going on with my leaves? Even the sugar leaves are starting to die. Sprayed with optic foliar switch to prevent male flowers popping up a few weeks ago so could be that.

Orange/Yellow spots on leaves
Today I noticed that one of my plants has an orange/yellow sign on a couple of leaves (see photo with the tag "28/02"). The spots are small and the leaves seem to be healthy (so far). What the problem could be?

Is this turning purple from temp change
So it looks like what I thought was a brown spot (under the grow light), appears to be purple when I pulled it out to get a better look and stake it down. I did switch the light to something cooler, could this be from temp dropping. Not worried yet, just curious. Thanks

2 out of 5 plants are showing signs of nutrient burn? Soil grow
Hi, I am seeing clear signs of nutrient burn but only on 2 out of 5 plants. I feed them organic nutrients, following the chart that was provided by BioBizz. Why are they still showing burned leaves? I watered them thoroughly until the runoff was clear. But leaves keep burning.😦

What is causing this Leaf discolouration overnight after a lot of tent work yesterday
Spent a lot of time in the tent yesterday. Everything was fine and this morning there’s bad discolouration on the leaves of some plants. I did lower the plant (was way too high) so may beight burn - but it’s only on some plants I did make two mixes of water/nutes

Brown Rusty Dots
What are these brown dots on my plants? They are only on one of the plants, they have gotten a spray with Dr. Zymes Eliminator and had no effect, also did a mL of Cal Mag in its last water with no effect and getting worse. I’m not sure what this is and I can’t get it to go away!

Flush or what to do ?
Advice please. I watered yesterday but the stains on the leaves are getting worse. Now I don't know if it is deficiency of cal n mag due to nutritient lock out which might be due to ph being off as I have 5 reders and all of them show a different thing. 🤦♀️...or it is it rust?
