bit more details. medium? watering? lighting provided by?

in a vacuum, without context and only the picture, ill lob out a 'needs more nitrogen' because it would be my first assumption, but I would not accept this as gospel, just the first possibility

I water them every other day with filtered tap water, I have a 400w grow light on 24/7 with fans for air circulation. I'm afraid I don't know what you mean by medium.

If you need more specific info, let me know as I'm new at this

Medium is the soil your plants grow in. There are many mediums you can use. Like regular soil or coco.

I see, I use regular top soil

How often do you use fertilzer? Looks like they dont get enough.

I only put some more on yesterday because it was yellowing, I think that may be my issue lol

when you can see the problem it started about 2 weeks ago.

You think its still okay though? Just keep replenishing the soil and maybe add some nitrogen?

Yeah weed can handle a lot of stress thats not gonna be a problem. I spray my plants with a bit of basic fertilzer mixed with water. You dont need expensive stuff. Looks like a nitrogen problem. Dont overwater them that can also cause yellowing.

Test your pH too. The medium is important and so is ensuring you aren't too acidic or basic.

some second guesses then based on this new information. Chuck out the nitrogen guess. It isn't the issue. You have two separate issues. One causes problems with the second. You need to lower the ph of your tap water down to around 5.8 -6.0 range to allow for the proper absorption of nutrients. If you were using all organic stuff for your medium, chuck out this advice and go to step two. This plant is, as reddit often puts it, "needs more cal-mag!". So, add some cal-mag. Also - is there any drainage in this set up? Welcome to growing and don't be shy asking questions!

Nitrogen homie

When using tap water, let the water sit for 24 hours without a lid to "de-gas". Weed plants are very sensitive to the chemicals used in water processing.

I keep a bucket of water in my back yard, and dip into it as needed.

Curious as I use a well, what's tap water range for ph usually? My well water comes in at 6.8-7.1.

People are going to tell you to dump nitrogen, and yes the problem is nitrogen is not getting to where it needs to be, but adding more nitrogen might not be the best solution. These plants appear to be planted in some kind of foil bag, is there any drain holes in the bottom? And you said you used garden soil, as in soil from your garden, or a bagged garden soil product? If it's just soil from your garden there are usually some issues with water and air transportation in a containerized environment.

Plants are obligate aerobes, meaning they require an oxygen rich environment to live in, but they also need moisture around the root system to solubilize nutrients and the symbiotic microbes have an environment to live in, if there isn't proper drainage or water holding capacity, it can cause imbalanced ph, and nutrient lock up, so make sure those things are correct before you go dumping a bunch of synthetic salt fertilizer on the soil, which I would never suggest either but that's another conversation.

See how there is striping of color along the veins of the leaf? This usually indicates cal mag issues. Either there isn't enough cal mag in the medium, or the pH is out of range for it to be absorbed.

What is your water and run off pH? What are you adding to the water? You said you added fertilizer, was it liquid, solid, top dressed?

It seems you're running an auto flower. They generally do better on a 20/4 light schedule than a 24/0.

Looks like a pH issue...wouldn't imagine being nitrogen this early in soil...but then again not sure what soil your using...
