Been a few years since my last grow but my problem was with taste. Two different strains with two different exceptional aromas. Dried and then cured for 2 months. Both green tasting still. Dried in the wrong conditions?
Sorry Lipa, didn't mean to take away from your question but your post made me remember. My harvest would smell and look A1 but then taste green no matter how many times I would sweat it or let it get overly dry.

I'm definitely not satisfied when my grass smells like grass.
It can come from different things: early harvest, shit genetics, over drying...
Make sure your humidity and temperature are proper. Slow drying is key.

Lipa - I had a buddy who's bud was always grassy or hay like, I personally don't like it at all, not to that extent anyway, and so I've been keeping an eye out for tips about how to prevent that.
What I've read in tbe other forums is that the grass smell is the chlorophyll still in the plant and it needs more drying time or a slower controlled dry.
I read thinfs like the plant is still alive after harvest and will actively convert chlorophyll into sugars during the drytime.
Drying over 6-7 days at 55-60% humidity is the goal from what I gather. Higher than 60 risks bud rot less than 50 dries too fast and doesn't give time for the conversion. I plan to use my smaller 2x4 tent to control the timeframe.
A lot of ppl use the boveda packs to acheive 62% or whatever but I've read of some vets that maintian the humidity during drying and simply seal the buds in jars at proper humidity and burp. That's my goal.

To avoid the green hay smell all you need to do is not trim your buds wet. Basically, remove all the fan leaves a couple days before harvest. Then just cut the branches and hang to dry, once dry do your dry trimming.
The scientific reason for the hay smell are GLV's (Green Leaf Volatiles). They're a variety of compounds with that green smell (alcohols, aldehydes and fatty acid esters) that plants release when their leaves are cut or eaten by bugs in order to either repel the bugs, warn surrounding plants of an attack, or help tissue heal faster depending on the GLV.
That's why I recommend to remove all fan leaves a couple days before harvest, it gives the plant time to heal and stop producing those compounds. And dry trimming because obviously the plant won't release those once it's dry and dead. But it definitely does when wet trimming.
If you don't believe me do a side by side, wet trim one branch and dry trim a similar branch, you'll see the difference in taste & smell is tremendous.
A lot less trichome loss when dry trimming too, no gummy scissors and you can trim over a screen and have a nice bit of dry sift to enjoy as a reward for your trimming work.

Agreed, dry trimming is ideal.

In regard to underripe bud giving the hay/grass smell.... would a blooming specimen w a terpene profile of say all cloudy/w a few sparse clear and a few amber here and there give off such an aroma? Keeping in mind that the unpleasant smell is only expressed after the blooms have been cut... when alive and vascular, they smell skunk.
Could light burn cause this as well. Not crispy buds, but tips that have been getting too much light... 
Fox that grassy smell!

Like I said it's the act itself of cutting the plant that makes it produce this smell. Generally if you just cut the branches and hang it's not noticeable but as soon as you start pulling leaves while the plant is fresh you're fucked.

Interesting. I've always dry trimmed myself, and the only time I've had issues with the hay smell is jarring it up to early. I like to put it in a brown paper bag a day or two now before putting it in a jar just to make sure. It sucks because once you get that alfalfa smell, its always going to be just that. I've seen some nice flowers end up like that because they were put into cure too soon.

That is one factor, but not the only one.

One of my plants was bleeding too. I wasn't sure if it was a bug or a scab that the plant made. What causes that?

Oh, so it is like a scab sort of. Mine was more mid-plant and wasn't topped. Maybe a bug bit it

It's just juice exuding from a fresh wound. Not sure what makes it red to be honest.

Pinched a couple tops in my day and have never seen red blood what kind of turbo organic nutes are you guys using? What are you running there rand... teas made from donkey souls and iguana bones... what, do we have some angel fearhers in that soil mix bro?

I have never seen it before this year.
I'm wondering if excess nutrients could cause the sap to be darker. Or maube its the opposite and my plant is healthy and full of sugars.
Or maybe it's just strain specific, since I don't see it in all of them.

Anyone have positive feelings towards adding co2 to your grow tent?
I've seen several people have the opinion that for the home grower it would make no difference but I've been reading a lot where if you have enough light and nutes you could benefit from more co2.
Thoughts?

Pretty much like you said, you have to dial it in with light and temp.
I've heard of people using oyster mushroom logs for co2 in the garden, but if you're trying to be precise with your ppm I'm not sure how effective that is.

I actually tried that briefly but that was before I put a humidifier in my tent and it was a chore that i wouldn't be able to measure anyway.
It would take a few grows for me to even be able to notice a difference in yield and it would be hard to say how much of that difference was co2.
I've had convos in mush cult about it and the consensus at that time was it was a marketing ploy (the boxes of mush co2 kits) but no one knows how much an oyster block emits during the day. So many individual factors including your grow tents ventilation system, how much can a few mush blocks around the tent help when the wisps of co2 that come off are immediately swept away by an aggressive ventilation system.
But the more I read and learn, the more I think any home grower who has serious lighting (which should be 35-50 true watts per square foot of tent), and who has a high plant count especially where it's crowded in the tent, could benefit from as much as you could cram in there.
With pinholes everywhere in the tent plus opening periodically plus vent system you can't overdue it on home scale. I think it's more correct to say, "absolutely it will help, good luck doing it cheaply and making it worthwhile"
I think it would require me to change my airflow, currently I draw air from in tbe tent through my 2 1000 watt hps hoods and out the tent and window, I would need to run a dedicated air intake line out the tent and hook up to my fan so the continuous bulb cooling air is not drawn from inside tent.
Then I'd need to add in a separate purge system on a timer with another fan kicking on to evacuate the tent once an hour or whatever.
