seems normal for this stage of flowering

how long you got left 3 weeks?

or it could be mag def, epsom salts may help

but wait see what the more experienced people think before doing the epsom

i had a plant exactly the same

search for "yellow fan leaves @ bottom "

Jchap's right about the yellowing in later flowering, it's normal. You want the N levels in the plants to fall later in flowering to produce a better product. Flowering fertilizers are much lower in N than a vegetative, causing the plants to consume the N from the leaves, hence the yellowing.

You need to make sure they are not yellowing too much, too early in flowering. Since it is only the bottom ones now, you are in good shape if you only have a few weeks remaining in flower. If you have more than the three weeks that jchaps suggested, you may need some supplemental N to keep them going.

It appears to be nitrogen related. I wouldn't worry much since you're near the end of cycle. It's not mag. deficency.

I added some Guano to kick up the N. I have to go 4 more weeks and don't want to run out. Its sort of like not finishing a race because you ran out of gas!

Week 6.5 and looking okay. Who knows, maybe a successful run with T5's is possible!

Do you have a circulation fan on em?
Looks a bit like too humid or soil kept too moist, (or both) but without all the required info, is just a guess.

Are you giving them any nutes or micro's? Do you use CalMag Plus?

From the last photo, I would suggest easing off the nutrients a bit.
I can see burn on the tips and edges of the yellow leaves.

Even with guano, you'll want to back off the feeding regimen during the last two weeks and just use water, maybe some molasses. All fertilizers, chemical and organic, need to be flushed from the soil prior to harvesting. They all leave a sharp aftertaste that's undesirable. The yellowing is normal, and you don't want to reintroduce too much extra Nitrogen that could promote foliage and rob you of any last-ditch bud mass.

Have fun with them... they look tasty! :jointsmile:
