Medical Cannabis Card holder. This is my 2nd grow and both grows have been great in a Veg and turned to disasters in Flower.
1st grow were 2 Gorilla Glue Auto Flowers - No need to even discuss these, they made it to finish line but it wasnt pretty.. The plants were entirely all yellow from 2 weeks into flower, I was never able to correct whatever the problem was.
Now I'm on my second grow which is a Blue Dream Photo Period. This plant and the autos were beautiful during Veg. The first week of Flower they go directly down hill. Now this photo period is doing the same thing. Started out as rust looking spots on the leaves then goes from there to yellowing. Since this happens on leaves anywhere on the plant and not just the bottom I assumed it was cal/mag deficiency. So I start adding 2mls of Cal Mag to my waterings. This doesnt seem to stop it and it just continues getting worse.
I use 170 PPM tap water( which i do not know whats in it :/)
Fox Farm Ocean Forest Soil in 5 gallon cloth pots
3x3 tent with a Mars hydro TSW2000 LED
Fox Farm Trio nutrients
Try to keep temps around 82 - I see them drifting up to 86ish sometimes because I only have my exhaust fan kick on once an hour due to the fact the exhaust fan will keep the humidity at like 29 if I let it run constantly. (its a battle in itself to keep my environment spot on) typically humidity will be around 45/50 when exhaust is off
I PH everytime I feed or water. I even PH test my soil and its in the 6's .. I feed by PPMs not by Fox Farm schedule (which is a joke) but the plant keeps getting worse and worse and im losing my freaking mind!
Any Thoughts on what the heck I'm doing wrong?
Here some pics but keep in mind its twice as bad now as I forgot to take updated pics.

I agree with what the other guys have said. One other thing, what is your light distance from the top of the plants? Although that doesn't quite look like traditional light burn symptoms, sometimes plants eat through nutrients at a faster rate when the light is close and simply backing off the light a bit helps slow down the damage IME.
