Odd spots on leaf

Whats up RIU! 3rd day in 12/12 I pulled my plants out to water and noticed brownish spots on a few of the fan leaves on one of my three plants. I looked all over for bugs or mold and didn't find anything. New growth looks good and my two others don't have the spots. Attached are close ups and pics of the entire plant. Soil is FFHF with 40% perlite. Water with tap pH'd to 6.5. Temp is 72-76 F with lights on and 69 lights off. RH 60%.
Thanks!

You should try to get that RH down, 60% is where high risk of mildew and mold begins. I'm guessing old minor deficiency that never really did much to it. Looks dark green, bit high in N if that isn't normal for the strain.

Thanks for the reply. I ordered a dehumidifier that should be in on Monday because I've been worried about that RH for flowering. I had big time noob difficulties when this thing was in early veg so maybe you're right, was a deficiency at some point. The strain is Mastodon from OGS and I was thinking they were pretty dark green but I don't know if anyone else has experience with the strain (LA confidential/Endless sky cross) who'd know if it's normal or not.

Looks pretty dark from the plants that come up in a search, so wouldn't worry about that.
