Are they getting too cold at night?Same issue again this year $100 to anyone who's got a cure.
Has anyone else tested their soil? The only deficiency for me was boron.
If this is occurring in multiple locations then soil isn't causing the problem. Possibly bacterial. I've been experimenting with aspirin, 325mg per 1 gal water. It is suppose to strengthen the plants immunity. Could it help? Ya got me but after two years I'd be willing to try just about anything.
That and your pH was way low. Disease of some sort brought on by poor immune system response.
Is my guess.
You have lots of plants.
Cull and move on?
I've seen this in specific cultivars but it didn't come with any mutated growth. Just purple genetics.
Mutated growth its gotta be a disease/pathogen of some sort. Your soil test was fine even before you added in all that chemical fertilizer. Well except your pH of course.
To fix a soil pH issue with plants growing in the soil. Good luck specially if plants already in the ground. Very difficult to do in soil for this round of plants.
Soil has a great way to buffer most pH amendments. You soil report should have made a suggestion to amend for pH? Adding lime wont change the pH over night it takes a while "in soil".
Interesting, and a real pain I’m sure.
How’s the ph of the soil for the girls with problems? Humidity still super high? Over 65 and you’ll start to get problems. Are you heavily feeding? What’s the temp at the root zone? I see you bury the containers. You mentioned that if you take the affected inside it starts to heal?
I Would lean towards nutrient lockout. Why? Either environmental, aggressive feed schedule, or bad ph. Feed schedules should be dialled in according to the environment to a degree.
Here’s a similar[ish] issue from a few years back:
Sorry, haven't read the whole thread. I have never seen anything like this. You guys keep it on the East coast, k?I've tried foliar sprays of aspirin and silica suppliments last year, basically the only thing that helps is keeping them as healthy and fast growing as possible.
Ahh...My new old friend....
I have been having this problem for about 5 years now.
I am convinced it is a new type of Phytoplasma...possible viroid or bacterial infection ....maybe a cross vectoring from leafhoppers carrying aster yellows, purpletop .etc or other known phytoplasma types.
Definitely not a deficiency or cold related in any way..
Insect vector of some sort...leaf hopper or mite/aphid...?
Starts almost always at flowering onset usually mid end of july and peaks mid august.
Begins on the growing tips and then proceeds to spread down the stem infecting other nodes along the way..you can actually see the threads of anthocyanin/purple traveling along and down the stem spreading internally from the infection point.
Very severe stunting and black purple anthocyanin build up..tastes terrible wont burn right etc..
i have used systemics to control it...and it will grow out of it after treatment...but i always remove it completely as soon as i see it anywhere, to prevent possible further spread.
Prevention is key to control, chemical IPM works, but is very heavy handed..
More info from anyone is very much appreciated.
reports found on the internet i have gathered it is also in hawaii "blackdeath forum thread somewhere" and the upper midwest from different posters with positive ID.
If you haven't had a run in with this yet..it is only a matter of time before you will.
20 years no problem...Now its every year at just at the onset of flower...Just like clockwork.
Keep the info flowing.
I didnt read all the posts, but this is a phosphorus uptake problem from either bad ph or nutrient imbalance.
you're crazyCall me crazy, but maybe you should read the thread before you decide you have all the answers.
My buddies happens in both soil, and Promix BX..... Also in different locations, miles apart.
Last year, we used Promix BX, and had constant unfettered monitoring everyday, AND also had plants in amended soil, 6.5 PH 50 feet away.
Hes having the same shit this year, though it hasn't reared its ugly head 100% because its usually worst when they start to flower, but vegging plants have also already been observed.
Grow the same seeds inside, in Promix BX, same fertilizer, and have never had this happen.
