Black/purple spots on leaves, brown spots as well

Sorry for the almost weekly questions, but I just want to be sure the plant is doing okay.

How is it looking? Some of the growth at the canopy is turning purple/black and as you can see some of the smaller leaves by the buds are turning brown or dying off partially.

It's grown outdoors in coco/perlite, it's a Gorilla glue Auto. I'm not entirely sure how far along it is. I feed it daily with half dose of Advanced Nutrients Ph perfect (Micro, grow, bloom) and cal-mag.

It looks to me like a tiny bit of bud rot, but I am not an auto person at all so wait for others who are.

I wouldn't be worried about the purples, but the partially dying off buds does look like but rot. Hopefully it's not widespread.

I hope not! I don't think humidity has been high enough for bud rot to develop but I have no idea tbh.

IF it was bud rot, I would want to harvest right away, right?

Or at least cut the affected buds off.

I hope I'm wrong too....It's a very nice looking plant!! It could possibly be just a dying leaf near the bud.

Honestly not at all happy with this grow. My first grow was indoors in a grow tent under controlled conditions. Growing outdoors seems more challenging. But I hope it survives, Gorilla Glue looks frosty as hell.

it's getting cold at night? lots of genetics will purple up when it gets cold. You may have a very slight Ph/Calcium uptake issue due to the small circular spotting on the leaves, but that could also be something else. I wouldn't be concerned.

If it's bud rott you'll see more silvery/gray mold type colours and you'll also be able to pull your sugar leaves off the plant with 0 resistance and the base of the leaf stem will usually show signs of mold.

To me it doesn't look like bud rot at all. I wouldn't allow water to sit on the flowers if you are concerned about molds.IMG_000116.JPG

I purposely dropped the temps a bit in my grow and get the same results. Don't mind the burnt to shit leaves. This grow was a stress test of a potentially hermaphroditic genetics.

I had an outdoor auto grow in a similar way, buds were ultimately underdeveloped and really didn’t taste good, though the plant had run its course. I unscientifically attribute this to limited light, and lots of cloudy, wet days were I live. Threw it all away and swore off growing autos outdoors, at least in my current environment. Indoors has worked great, but they receive an unnatural amount of light.

If you're not having good luck with Auto's try growing photo's 12/12 from seed. It's cheaper than growing auto's and to me the results are better and you can clone.

It is getting cold at night yes. Thanks a lot for the input. I haven't been checking my ph at all, since "Ph perfect" allegedly should handle that. Maybe I will check at the next feed.

I will move the tree further into the shade to avoid water hitting it at all, good call!

Looks like you have mites as well

I'm not sure, I can't seem to find any mites on the plant. I did have thrips at one point earlier in the grow though. I will try to keep an eye on it, perhaps spray it all down with pyrethrum extract, shouldn't be harmful to flowering plants, I hope.

Or is the webbing a sure sign there are mites? Because there are regular spiders on the plant as well, like with regular webbing.

U looked under your leaves? The white dots look like bite marks

I did, I didn't see anything. Maybe I'm just going blind. I will check again tomorrow and spray it down just in case.

Do you have any ideas? It's a bit late in flower to be spraying with most things, other than pyrethrum
