On some leaves on most plants they are brown marks I have attached photos.
My plants are week 4 of flower.
They are in coco the temp is 29 degrees and 55% humidity.
They are in coco and I am feeding shogun nutrients daily.
Any help would be much appreciated
Thanks

What you using for water? My tap water does that with ph down. Cal Mag Always fixxes this issue for me.

5.8 ph 2EC
Haven't checked my run off in a few weeks.
I'm changing to RDWC after this run as I find coco to be a bit too much guess work for my in experienced self.

If you use ph down, it may be a micro nutrient difiency. My tap water comes out at like 8.5 - 9.0. Usually about two or three weeks in, if I dont use cal mag. My plants start looking like yours. Now I just start cal mag at like two weeks.

Raise the pH to 6.1 and you will see some improvement.

Also I would recommend doing an inspection for bugs.
