Welcome to 420 @jro0069
In soil it's probably a combo of the two - you could try a shot of liquid PK but assuming it's due to ripen in the next few weeks I wouldn't be too worried

What fertilizers and schedule have you been using up to now?
The Jorge Cervantes chart showing examples of deficiencies keys in on a Potassium shortage. The Darwin's Garden deficiency chart is close to the same. I have another chart also showing a similar looking example for Potassium but I do not know whose chart but I suspect it was from someone in Greece or Turkey.
It looks somewhat similar to a Calcium deficiency but that usually will start to show much earlier before flowering starts while Potassium tends to show up shortly after flowering starts.
Potassium is needed for overall plant health. Figure that the damage done to the leaves already will not go away. Start feeding with a Potassium source as a way to slow down any new damage.
As @Roy Growin hints, if the plant is 6 weeks into flower, you might be able to get by as is. I figure a dose of Potassium might help with healthier buds. For soil grows look up Kelp Meal, a tea or top dressing made with Kelp Meal, or one of the Kelp products for using in the future.

Fox Farms and Cal Mag. It's funny because not all the fan leaves have the issue, only a few. Thanks for the reply SW!
Lower part of the plant, right?

If it's a peat based soil mix your pH buffer is probably running out. All peat based "soil" is more or less amended with lime and gypsum to combat low pH. This needs to be replaced in mid to late flower and taken into consideration.
Over fertilizing often leads to low pH also, like using PK boosters that are not in any way needed growing in containers and quite contra productive since the plant can't use the excess and the result is only low pH and lockouts in the medium.

a look at the entire plant would be a lot better than just a couple leaves. the leaves could be worse than what is happening or better.
if concerned you could just ph your nutes properly when feeding.
