Fusarium?

    Greetings. I was growing three plants in a 3x4 living soil bed and I was 7 weeks into flower, the first plant got hit with an abrupt wilt, after a few days of no improvement, I chopped. a week later, the second one got hit, I chopped, then the third plant. All have been harvested and are hanging. I’ve got good genetics and was planning to run them for 9 to 10 weeks but I’m trying to figure out exactly what the issue is?
    There was not any kind of leaf fade or necrotic spots creeping in, no fungal growth on the stems. The roots are still white looking, and there’s no redness in the stems.
    My research leads me to believe it may be fusarium as my humidity was a bit high in the 70’s some days and I did aerate with lava rock but maybe drainage might’ve been an issue.
    Just looking for a little guidance on this one if anyone has ever experienced similar situation and is it safe to consume these buds? ( no mold or rot, just dead wilted leaves). Thanks

    Sorry to hear of your troubles. I have no expereince with thses types of wilt. I did find an interesting article about them.
    Wilt diseases in hemp and their management in the Pacific Northwest
    I'll stick around in hopes to learn something new from the more knowledgeable folks here on GC.

    Thanks Tim. Appreciate the link. A big concern to me is if it safe to consume these, they look like pretty healthy buds under the leaves but I ran across an article that suggested trashing the crop and starting over if it was fusarium ( but they weren’t in the harvest window).

    Here’s a pic of one of the stems, I know the hole in the stem can be common but maybe this will aid in figuring out what’s been going on.
    I’ve had three of my best harvests in this bed and i thought i was on cruise control, and then… bam!
    I really didn’t want to dump this soil, it’s loaded with life :(

    I'd cut into the stem and compare it to that link. If it is one of those wilts caused by a fungal infection. I'd research more about consuming it.
    EDIT: I see you already did that.

    I think I'd look at the lowest stem portion near the soil line.

    This is what I use

    It kinda costs too much so get smaller portions if you can and store it in the freezer.

    Sorry about your plants. I've been having 6 months of 'starting over'... part of the game.

    If you want to salvage anything, I'd hit it with a UV light first (like for 30 min).

    I am not an expert. but I started looking for information about the subject since my plants have similar symptoms, the fan leaves are turning yellow and curling up and drying up, but the buds are beautiful and look very healthy, in my case I don't think it is fusarium since the fusarium attacks the stem and the damage should be reflected in everything that is on that stem, leaves, flowers, fruits. I am going to wait one more week since it is in its final stage and at any time I harvest it, to then check if the flower is healthy to be consumed, from what I have read many people present these symptoms in the final weeks of flowering, some people think that this is the sign that the flower is ready and ripe.

    The fading of leaves is a good thing in late flower, but that's not what's happening in the second picture.
