Help with identifying issue. Does anyone have any suggestions?

Hey everyone!

This is my first time grow and I can't seem to identify what the issue is. The leaves started out with brown spots on the fan blades then it's progressed further to what these photos show. Should I cut the affected leaves off? Any help is greatly appreciated!
-Strain: Jack Herer Autoflower
-Soil: Fox Farm Ocean Forest.
-Nutrients: Fox Farm Trio (just using Big Bloom currently) and Cal/Mag. I'm doing 2 tablespoons of big bloom and 2 tablespoon of cal/mag.
-pH: 6.2
-Water: purified
-Light Spider Farms SF2000
-Temp:72-85
-Humidity:46-65%

My experience is limited but it looks like over feeding/ over watering issues as well. I am sure many other more experienced growers will chime in. These carts can be helpful.

This is what it first started to look like before adding any nutrients.

Well .....

First your PH is too low ..... FFOF out of the bag is 6.3. therefore you should be at 6.5 to allow for drift.
This is why some element deficiencies are showing. FFOF can grow an auto on nothing but water.
Autos need only about 90 days of happy stress free growing ( average ) , FFOF can feed an auto for 6 weeks all by itself.
Big bloom has micronutrients and is the only organic of the trio set.

Shockingly , all you need to do is scoop some fresh FFOF and top dress your container / water in at 6.5 .
Add about 1 tsp of calmag per gallon to water . Leaves will not recover , you are just putting brakes on issue.
If auto becomes further stressed , it will stunt , slow or grow pathetically. Autos are plant and play , nothing else.

Surprising how many struggle with this simple peat based mix. It runs a bit hot initially but plant works thru it and acclimates.
Correct the PH and recharge medium as mentioned. Simple.

Thank you so much for this insight! I really appreciate the feedback on this and I'll make sure to follow your instructions. Would you suggest cutting the affected leaves or just let them die off on their own? If the plants are showing too much Nitrogen, would adding Cal/Mag make that worse?
