What medium are you using? What nutrients and/or supplements? How often are you watering, and at what pH?
Looks like classic magnesium deficiency to me. Ive seen the same on mine from time to time. Ph or root issues could contribute also. You giving RO water? Tapwater? De-chlorinating? Over or underfeeding? The (slightly) healthier leaves above are starting to show interveinal yellowing and will get more pronounced if issue isn't resolved. Those lower leaves look like they've given everything to the cause. May as well remove as they are done. If the root zone is healthy, adding cal-mag may resolve it.

Sohum "what cannabis craves" just transplanted them on the 10th of this month, like a little more than a week ago

I have calmag, is it possible that its potassium deficiency? Reason I ask is because there's a chart Online i looked at and the potassium looked like the interveinal yellowing to me.
I have been ph-ing my water (declorinated tap water) @6.4 - 6.5
I think I see stems reddening also which I think can indicate magnesium deficiency. Others here with way more insight than I. Probably best to list all your parameters such as soil, nutes, feed/water frequency with ph ranges, etc. Day/night temps. The more info you can share, the more likely someone here can more easily nail down the culprit. Meanwhile I think I'd start by removing the spent yellow leaves followed by introducing cal-mag and monitoring the interveinal yellowing of less affected leaves. If I doesn't get worse, you're on the right track. If it continues worsening, it's something else. Either way, addition of cal-mag in itself won't have had any ill effects. Addition of soluble beneficial microbes wouldn't hurt either to help ensure a healthy root zone.

From my 20 years of growing I can tell you you are over feeding causing lockout. All those clawing leaves are about 2 burn. Your newer leaves all have bleached/burnt tips

Feed that plant at ¾ what you were and she will likely improve

The soil is sohum what cannabis craves, the nutrients are already in the soil. The only other thing besides declorinated tap water at 6.4 ph that ive added is recharge. The temp during the day is around 78-80 degrees, at night around mid 70's. If its really humid out and im running the dehumidifier the temp at nights around 75- 77. Im running a 240watt led ac infinity light. Its running at 60% power and about 13 to 15 inches away depending on what plant. Any other questions pls ask as im sure my dumbass forgot something.
Also i was at my local hydroponic store and the guy told me not to ph my water higher than 6.2. Specifically 5.9-6.2. Is that right?

Tks for your time
Sounds like he may be referring to ph for hydro. Ph for soil grows is usually a little higher. Im not familiar with your soil type so cant say. Maybe i need to educate myself about it. I run happy frog and water around 6.3 has been working well for me.
Edit: not seeing any glaring thumbs down with the soil. I did see they have excellent customer service/ support. Maybe drop them a call. Could be that some gets by QC with insufficient amendments occasionally.
Re-edit: or maybe too heavily amended resulting in lockout as mentioned above.

Idk how im over feeding all the nutrients are already in the soil. Its "super soil". So are you indicating that im feeding to much by watering to much?

You just transplanted into soil that is to hot for the plant. Maybe your roots weren't healthy or something like that... but the plant is pulling nutrients from lower leaves because it's not able to uptake from the soil. Do a slurry test and check your ec and ph

It's a nitrogen deficiency

if your soil has all the nutrients already in the soil and you just transplanted than why is it eating itself alive ? like your plant is literally eating the nutrients in the fan leaves because it cant uptake nutrients from the root zone. so either your rootzone has no nutrients or you have lockout thus you cant uptake nutrients via the roots. maybe im wrong af lol i dont use super soil

You have a nitrogen deficiency, feed them some low dose veg fertilizer(salts). Or a bit of fish fertilizer if you insist on staying organic. The fertilizer salts will correct quickly, the nitrogen in the fish will take some time to break down and become plant available.
I’m guesswork this is your first grow. So go to www.growweedeasy.com and follow their basic grow guide. Don’t get discouraged it’s pretty easy if you just follow the instructions
