Not the best time to be straigtening out a problem like this... They may start dropping the leaves that are turning... Check for good drainage, fungus, and or fungus gnats. Could easily be a nutrient or soil problem...

Its the light dude we cant see the plant well..

My new friend. Please, please post a picture of your problem in natural or white light. This picture cannot work to identify anything for sure. Also, what are you feeding/not feeding them ? What are they planted in? Clones or seeds? Strain,? Oh there are many, many possibilities

Well just looking at the leaves,not even knowing how old or far along the plant is...you have large fans that appear nitrogen deprived.Some smaller leaves appear very dark green.A full plant picture would have been nice.

The plant is in flowering, it sprouted around november 10th. I ran into some problems so it isnt as big as it probably should be but they are doing quite decent other than this leaf issue. I kinda figured it was nitrogen but just want to get some better opinions before I fucked shit up
I can get a pic if you absolutely need one but Id rather do that tm if its a must, cant really get into why..
But what else could this possibly be do you think? Just based off what you saw already

Lack of nitrogen uptake looks like the most likely answer, because they are at the bottom of the plant.
If they were newer leaves at the tips, I'd say probably lack of iron uptake.
Such a deficiency can either be caused by too little of the nutrient in the growing media/water source, or, some other problem causing the plant to be unable to uptake the nutrient.
In the case of iron deficiency, the culprit is more often too high PH, than too low iron levels.
Similarly, nitrogen deficiency can be caused by too low PH, not just too low nitrogen levels.
Do you PH test your tap water? And test it after adding nutes? And test the runoff coming out of your pot?
p.s. Some yellowing like this is normal and even desirable in late flowering. It's a problem worth fixing only if it's happening in the veg stage, too early in flowering, too quickly, or as a result of too low PH.

Thank you green. I kinda assumed that was the problem but didnt know forsure because I do in fact test my water after the nutes, but I usually tried keeping it on the low side just because I thought it was safer.
I use strips too, my meter isnt calibrated correctly, so I never know what the ph is forsure.
Welp, thanks, lesson learned.
Thanks a lot brotha
