Looks like a deficiency to me. Double check your temps and humidity to be sure, but I'm thinking that's not fungus.

Unknown rust on 7th flowering week This started as what I thought was a cal/mag deficiency, bought some, gave it for a week at a good dose and 6.3ph, and this intensified and switched from just lower leaves to the upper and a few sugar leaves on one plant. Any ideas? May calmag takes awhile? Or wrong diagnosis?

The last few days I had 3 plants start not looking so hot. The 3 pictures are the 3 plants when I got home today. I haven't really encountered deficiencies, if it's even that. I'm watering at 5.8 and last I checked the runoff a 2 days ago it was 6.8. Any ideas?

Brown spots, serrated edges curling up - calcium deficiency?This is a Barney's Critical Kush auto that's at about day 57. She's into flowering, but I've just started to notice some brown spots on leaves with some slight tip browning, and the serrated edges on the leaf are curling up. Is this just a straight calcium deficiency?

Orange Spot in first set of leaves If you can see Veg Week 1 Photos, Photo named Day 7 Zoomed, I have been seeing these dots for 2-3 days now. What is it? how can it be solved? FYI - These were the first set of leaves, others look healthy. My guess - nut water got sprinkled or cal/mag deficiency.
