Yellowing fan leaves during flowering. common? do i cut?

The leaves turning yellow does not mean the buds are ripe. You have to check the status of the trichomes for that, or look at the hairs as they go from pure white to brown or orange. When production of fresh white hairs at the top of the bud slows, and the hairs are turning brown much faster than they are being replaced, you are getting close to harvest.

Don't give a flowering plant N just because the leaves are yellowing! You don't want it resuming vegetative growth.

The yellowing is natural, but sorry cannabecea that looks like you have a light problem and the yellowing is from not enough light getting to the plant. The leaves should not be that yellow in that early a stage of bud development.

Yellowing of a few lower leaves is normal just let me fall off. Any more than a few lowers and you may have a porb.

yes,,,, correct..
Swolen,, it is normal for a plants levaes to yellow during flowering... but not the way yours are yellowing.. if the plant is healthy and getting proper nutrients with proper PH.. then the leaves will yellow from the bottom of the plant to the top,,,

your plant is nutrient starved.. it is HUNGRY.. it may be to late to fix it and you will just have to take a GOOD yet smaller yield than what was POSSIBLE/potential...

the leaves of a flowering plant that turn yellow can be pulled off with a simple and gentle tug.. if they do not come off easily, let them stay.....

I suspect the plants did not recive adequate NITROGEN during the vegging stage.. Your plants look healthy.. YET HUNGRY...

and NOW you KNOWM

(soil) 4 fotter 20 fat tops 3.5 months old 400mh veg ,400hps flower. 1 topping and pruning right before flowering cycle.
thanks

This is a pic of my plant and as you can see its quite yellow (after i took the shot i harvested it). and YES INDEED THEY ARE SMALL coz i grow only for myslef and smoke like 1 time per month so i don't really need too much to keep me going

see ya peace

If you harvested right after you did probably about a month early ...lol look at the pistils????

Ya know, this thread is six years old. Its evident he harvested too early, but it doesnt do anybody any good at this point. Ha. Plus, you could have posted those pics in your own thread in the Grow Log section.

how are the plants?
