From the photo it don’t look like a big issue looks to be a burn from water or moisture sitting on leaf in the light

Anyone know what this is the beginning? Looked at the pictures of different deficiencies and excesses but the all seem to look similar off the start
Wonder if anyone can give me a diagnosis on what this is the beginning of? She is coming up on 6 weeks old, haven’t had any issues so far. Happy frog soil, no nutrients yet, strictly PH’d water between 5.9 and 6.1 for each watering.

One weird unhealthy leaf?
I was just checking my girls when I noticed this leaf hidden away. I have no idea what it's from, so I thought I'd ask here. There was literally 1 leaf like this on the entire plant, I couldn't find another, although it's in a hard to reach spot. Any help is appreciated! 🙏

What is this rust discoloration on leaves, and how can I stop it?
Does anyone happen to know what is causing this rust colored discoloration on fan leaves? It starts on bottom leaves, and moves up. Also seeing yellowing on leaves, and not sure if its pest issue, light issue, deficiency, or watering concern. Super nervous plants are dying🙁

Some leaves are affected by leaf miners, the two on the bottom, in particular one of them, the plant hasn’t so much leaves so is better to cut them or leave them?

Leaf Discoloration
I woke up this morning to only one of my strains having discoloration on the leaves. Still looks extremely healthy but I don't feel like I'm overwatering and I'm definitely not over fertilizing. Need help before problem gets exacerbated. Thx in advance.

Hilfe!!! Was ist das???
Sind das trichome oder mehltau? Kann eine Pflanze mit 2 Blätter überhaupt schon trichome haben? Wenn ich draufkucke sieht es aus wie kalk. Lässt sich auch nicht wegwischen. Mehltau ja eigentlich schon. Was sagt ihr?
