Should I cut off my yellowed leaves?

no, why? the plant has mobilized nutrients in there
it will use them up sooner or later
the last couple weeks of flower it will pull nutes from all its leafs
or if you mess up nutes again before then

well said.
However, if discernible necrotic spots appear, it may be wise to remove them, just for molds sake.

When the leaf is entirely necrotic ( dead brown crunch crumbly ) cut up to not beyond the necrotic parts to remove rotting tissue, chlorotic ( yellow, green, red, pink ) make like the tree and LEAF it on
when a leaf is ready to go just give the stem a tap with your finger , if it is ready to go it will fall off automatically from that small movement.
Cutting can make wounds and cause mold. But if you have a big outdoor plant cutting the inside leaves and branches IS a good idea to promote air flow and light

I'm with the trim crowd. Granted there are stored nutrients there and cutting can cause infection issues, but I have always trimmed off leaves that are more than 30% necrotic. This way I can see if the problem is persisting or not. If you leave all the yellow leaves on there you won't be able to tell a week from now if they are newly showing or just the old ones. Makes it harder to judge the plant's current health IMO.
Make sure to make the cut leaving about 0.5-1" of leaf stem so that if there is an infection, it might not reach the main plant before either you notice it or the stem falls off from the plant taking care of it. This is my impression, and I have never had any problems this way. It might even help with light penetration.

When your plant is done with a leaf, it will let you know. This is information that more than one person in this thread has offered and it's good information.
If you cut parts of the leaf off, you're forcing the plant to heal itself unexpectedly, causing stress and possibly wounds/mold. When a plant is finished with a leaf, the plant will have started to develop scar tissue where the leaf attaches to the stem and prepared itself for the loss of the leaf. This is why they come off so easily when they're through with them.
Taking leaves off before their time or "trimming" leaves to remove dead tissue is an invitation for stress and problems and doesn't allow the plant to do its thing.
if you're terribly worried about actual dead (necrotic, brown) tissue, you can use your hands to crumble or break off the pieces but don't try to cut next to the living tissue because there's a big chance you'll miss or get too close to living tissue and cause further stress. But again: you're not really "helping" anything, you're just getting rid of dead stuff.
Honestly, if your grow is in a condition where a tiny amount of dead leaves are going to cause mold: you've probably got bigger problems than colorful leaves.

I know they look like shit, but yellow leaves are bud food....no cutting them peez

I grow bushs I trim on a regular basis to allow for good light penetration. I am selective when I do it, and I don't stress them during peak stretch or flowering. I take half a black trashbag full out normally when I do, off 12 plants b4. I LST, supercrop, scrog, and top, I have to sacrifice whole stems 3 ft long because they are being beat out by the competition. In most cases I would say no don't touch them, they are not done using them. But in some you just have to to make good use of your budsites and lights.

being a new grower, i cut off some leaves that were severely damaged from cal/mag deficiencies, not to mention some of them were shading other budsites and other lower leaves.
try to keep them on as long as you can, but no, yellowing...i wouldnt...diseased, rotten, or practically damaged beyond all repair...if necessary...go for it...ive never seen people cut off leaves and cause mold. keep good airflow and humidity down and mold wont be an issue. i cut off a ton of fan leaves and my bitches are FAT! harvesting shortly and mm do they smell good

That's the truth.
However, I'm with KMK in that I've never seen someone cutting off leaves that caused (he said mold) any real problems with the plants. I wouldn't do it once flowering set in, and honestly, it might slow veg down a little, but I don't consider that a big deal. I also don't think my plants have feelings, so I'm not crying when I have to give them a hair cut, ya naw mean?
I have, though, seen a single dead leaf, fallen onto a bucket lid, growing small amounts of that weird mold that looks almost like trichs but the wrong color. This is because mold spores are impossible (IMO) to totally eradicate from a grow (and that's ok). If you have dead material in the grow room, though, you are creating ideal conditions for this small amount of mold spores to thrive on/in. That's my point.
