Is this fungi or nutrient burn?

Hey guys, this little girl is having problems and I’m not sure what is going on. I’m really new at this and I’m a little lost on this part. Seems like fungi, but the pictures I have seem of actual fungi are a little different.

They were out of water for almost a week (they are in a big pot and they don’t need that much watering), and I watered today.

I trimmed the leafs off, but if it’s actually fungi, I don’t know how to fix it.

Can anybody give me some advices please?

This was your problem, along with your ph probably being off at the root zone. What is your ph in/out and what brand of nutrients and soil are you using?

Doesn’t look fungi related to me
