Rust spots on fan leaves

Just wondering if anyone has any ideas of what i'm fighting here. It's not widespread and doesn't seem to be spreading too much either. I fought this a bit last grow and it didn't affect the plant much. But it's happening again this grow and now i'd like to figure out what it is.

I'm in 3 gallon fabric pots. FFOF soil. 250 actual watt LED. RH average is 45%, Temps range from 70-84. This plant is a Blue Dream auto from Fastbuds that is 29 days old. Fed 1tsp calmag per gallon of water from seed. Didn't add anything else until 21 days. I've been watering with tap water that has sat out for 24-48 hours (this is getting rid of all chlorine. Could I have a chlorine deficiency?). Adding 1tsp of calmag, 1tsp big bloom and 1/4tsp tiger bloom per gallon of water. Watering every 3 days until I get a bit of runoff.

Here's a pic of the girl and 2 pics of the worst fan leaves. It is affecting 4 of the largest leaves and maybe 1 or 2 smaller leaves.

Any help is much appreciated.TE

I actually just noticed some spotting on mine too. Danmitch1 sounds correct. They've been very healthy up until now so I'm hoping it doesn't effect the end result
