Do a slurry test if anything.
Still unsure as to what is going on, need veteran help PLEASE

Like PopAndSonGrows said, quit chasing the pH out. If you pH the water or feed, that's fine. Don't worry about it on the way out.

Runoff pH is useless information. A waste of time. Concentrate on the pH going in. It looks like phosphorus deficiency.

Just feed with normal tap water and feed wich should be higher than six. It should balance you ph in the soil to six or slightly higher. In soil the microbial life adjusts ph level to what is gois for the plant anyway. A bit of swing from 5.5-7.5 is fine and it should stay in that range.
What light are you using. Under led plants can use more nutrients so you probably need a complete feed, flushing is probably going to make your issue worse.

My bad I didn't see your comments. Yeah ph has been on point my last 3 waters, I used calmag this last time but it was having issues before I ever did that. So I should start feeding again then? And maybe go with a heavier dose? This is the largest plant I've dealt with. I've been micro dosing it feed wise, because its a autoflower.

Well yeah, micro dosing = deficiency. Don't go "heavy", just go with a regular or medium level feed.
You may want to consider switching to growing in coco? Reason I say that, it's much much easier in terms of "set your parameters & go"; you don't have to worry about overwatering coco. You just have to give the same level feed every day, which eliminates a lot of guesswork. Whenever you're watering coco, you should be feeding it, to runoff, so that it doesn't get over-accumulation of salts or minerals. The term is "fertigation", it just means having nutrients in your water.
The manner in which you're growing is already kind of coco-style, including the haphazard addition of calmag; in coco, you're most certainly gona need to add that. Best of luck either way

If you're watering to runoff, in soil, without adding nutes, you're overwatering. What do you have for nutrients, other than calmag?

I was only watering to run off to test ph, but I also did that every once in awhile to reduce nitrate building up. I've been avoiding adding nutes since this issue arised and I was not sure what caused it. I have the fox farm trio. I suppose I will be upping that next time I need to water, or sooner since I'm being told that is the cause.

Lookup cannabis septoria. See what you think.

I can assure you that you have a ph problem.. I see manganese deficiency up top and Marcos down below… that soil should have plenty of trace minerals left at this point… most can run ffof with autos to harvest without adding nutrients.
I will also bet if you test your runoff you are in the high 5s ocean forest has a tendency to become acidic for beginners which improper watering practices.
You can follow advice above and just start feeding trio but if you can’t correct ph you will only make things worse, your first thought should never be just add more.
PS. FF trio is very salty, follow their flushing schedule, you don’t need a product to flush you can just use water.
I couldn’t tell you how many times iv seen fox farms soil out of the bag with super low ph, I was just at a first time growers house and he had a ph of 4.9 out of the bag (happy frog).
make sure your equipment is calibrated, iv seen that bite people also.

It looks like it's in a bucket, does the bucket have holes in the bottom to allow for drainage? The yellow leaves looks like a nitrogen deficiency. I'm not sure about the brown spots though.

Water with Baking soda, hydrogen peroxide, and vinegar. I use mostly baking soda because I like it that it’s most natural and easy to work with. Milk is bad for plants.

See thats what I was thinking. I'm getting confused by everyone saying its not enough nutes then not right ph. Also I'm testing ph with droplets, so there's no way for it to be inaccurate albeit a slight bit hard to read since its color based. I'm going to try and raise the soil pH today, and add some nutrients. Remember its a mix of ffof AND black gold which is a much milder soil

Blah I'm getting confused with this thread. Some are telling me its a ph issue. Others are saying I need to feed it. I'm going to hit it again today with a water to get it nutrients and hope for the best. Its under 3 lights, 2 or my old blurple mara hydro 60w and a 100w spider farm led.

The best thing you can really do imo is make your last change then stop changing things for a few days and see how the plants react.
If you keep changing things or change multiple variables at once you can be creating other problems while trying to fix one.
For example, you were basically not feeding but you went and flushed or tried to, this will remove nutes and ph buffers from your soil. If this is a deficiency that would exacerbate the issue.. You also have to remember if you flush after you want do so with a mild nute solution or you are basically just depleting the soil and leaving nothing for your plants.
When watering ff soils you typically only need to adjust ph if it is low, the soil will buffer a high ph down but tends to not do as well with raising low ph. I would let the soil dry back to your normal watering point and then water with nutes

right here… exactly what I said. Changing to many variables at one time could lead you into fixing a problem not knowing what corrected it, or causing others at the same time, this is exactly why I suggested to test before adding or doing anything.
It’s always good practice to eliminate possible causes before throwing the kitchen sink at it.

I water to just a tiny little bit of runoff just to know the pot is saturated enough after a good dryback, is that alright for tap water and top dressing only?

I think PH, too. but I'm still trying to get people to look at those pictures. Dream on if you think that stuff is going to stay in Calif. There's going to be a whole new war to fight when it starts to spread. Anything I don't recognize I compare to the photos on the web. Maybe it's this, or maybe it's that, but at least I've seen a picture and know what it might look like.
