Pictures.
Pictures, or at the very least info regarding your set up.
Some plants just have a purp pheno, low temps late in flowering will cause the leaves to purp up nice.
The yellowing is a Nutrient or Ph issue, which one is what we need more info to discern.

I would bet you have two things going on..

First, you need to get some N to that baby.. she is very hungry.

Secondly, I would ask if your night time temps have been getting colder than usual? That can cause a bit of slowdown of P (or is it k?) uptake causing some bluish/reddish hues in flowering.

Phosphorous Toxicity causes purple leaves in flower, And also purple leaves for deficiency in Veg.

Nitrogen Deficiency would be correct for the yellow..

What nutes do you use??

How much Molasses?
You can smother your roots if you use too much.. You probably know that though right?

Don't do anything. Not yet. If it's just a couple leaves. If it starts to get worse then you may have an issue. but for 1 or 2 leaves to be discolored. it could be an old issue that has been corrected but the leaf is still going to continue to fade.


If you have a bunch of leaves different colors in different spots then you will have to figure out what to do. but for now. nothing.

If it is an N deficiency then your plant will continue to yellow. if that happens use MORE Nitrogen(usually adding a little Grow nutes to the mix will help)
If it continues to purple, it's either A too high Phosphorous(which i do all the time to get Purple plants)
or B your temps are dropping MORE than 15 degrees F over night.(which is also not much of an issue)

Good luck

I triple my BioBud(General Organics) to add purple to the plants. it works. even when you can't achieve the low temps at night.

I'll stay subbed up. but WATCH THEM... don't just assume everything is ok because i told you not to do anything.
I am saying it could be nothing because the damage is so confined to a few leaves. IF it gets worse, post the pics and most of the people on here trying to help you including myself will do what we can.

Which pic. you posted 3 and 2 are blurry. so i don't know what you are referring to.

If you are outdoors what are your night temps? they could be the reason for the purple if more than 15 degree drop.
