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.

Deficiency?
I laid off the nutrients last week after some concern that I was overfeeding, but I think that resulted in a deficiency. (Some of the darker colors might be related to the strain? 🤔) The third picture was taken 12 hours prior to the first two, so it progressed quickly overnight

Leaf tips are browning
Ciao tutti, What is going on with these leaf tips? It’s the third day of their Flush & It can’t be NutBurn, or the color of tips doesnt look like NutDef! Is the light stress? If this de-coloring continues, will it effect the buds & final yield? Thanks

Day 14. Since day 12 a brown spot has appeared on one of the leaves of the first node, spreading little by little. Because of the symptoms, I think it's septoria, so I've sprayed neem oil to see how it works for her. Someone knows what can it be?

Brown Edges on Leaf. Bit of yellow and purple.
What could be causing this? And how do I fix it with GH flora series. It is only showing up on one bud site. But I believe its getting worse. I also noticed other leaves all of the jagged edges are slightly curled up

What's going on with mk Ultra? It gets Neem every 2-3 days, and I have tried to keep pH down to 6. This has been going on since I got the clone, and it continues to happen. The pink kush (last pic) has a few similar spots. Lights are 50cm above.

Brown dark spots on fan leaf
Any clue what this is? It only appeared on 1 of the plants and only on 1 of the fan leaves. The brown color has kind of a metallic shine to it. My guess is that it’s a Cal. def. I also suspect it might be a Phosphorus def. as the plants turned dark green the last few days.
