Brown spots on the lower/middle fan leaves in flower week 2

Hi there, Honestly nothing to worry about, I have them on lots of my plants when they’re small in veg. It’s generally down to PH fluctuations usually due to adding/removing nutrients to your feeds. I would expect everyone else who comments says something similar. I honestly don’t worry about it anymore it doesn’t cause me to lose sleep. 👍

If your worried start to look with a microscope up and under the leaves. if the soil is fertile and hit the leaf - can cause that. if a water drop on her in the sun - Can cause that

Pics 1 and 3 look like they might have had droplets of water on them and caused some burn spots. Pic 2 looks like a leaf miner. For the leaf miner simply squeeze the leaf between your fingers where the line is. That typically kills them. Good luck 👍
