WTF is this crap?

This one looked pretty frigging good 3 days back. Fell off fast after I quit watering. Other pots dried back but not this one? Fucker was heavy, didn’t suck up any water? It’s cut and hanging now.
Avenue of the Giants. Plants been brittle all along. Listed as an 8 week strain, which I hit. Maybe it just ran out of gas? Roots were damp as expected with a heavy pot, but not slimey. Leaves drooped, then got crispy fast. No sign of root aphids or any other bugs. Couple spots of light PM. Can PM present like this? Had a bit in the stems.

Was water tap, rain or R/O? Do you know PH of the water?

A friend ran into this issue up here with our very hard water in Guelph…that branch crisped up fast too after being limp

Just harvest the branch; put it in water if you’re so inclined. :man_shrugging:

:evergreen_tree: so helpful l, I know :sweat_smile:

I’d trim it and pay careful attention to rot.

Whole plant, not just a branch. I fill 5 gallon jugs. Let them sit a day before use just cuz. Water comes in 200-250ppm, ph has been running about 8. After nutes, I ph 6-6.4. Peat and Perlite. Lucas feed. My last run-off ph was 6. Run-off is usually pretty close. Ph tool gets calibrated regularly.
Not really a problem at this point. Nothing I’ve experienced quite like this. But if I was at 6 weeks I’d be worried. Be nice to avoid.

how bout crushing a viagra in some of the water? lol my daughter just looked over my shoulder and said you aint right :grinning:

Viagra? Shit. I get so excited just looking in the tent, I need to be careful not to zip-tie a branch to myself.

Yea, you need to clean the stains off the outside of the tent, it is getting crusty…LOL

My guess is Fusarium

What is Fusarium?

Fusarium, also known as fusarium wilt, is a fungi-produced illness caused by fusarium fungi, and it’s quite common in cannabis and other grows. It’s also present in human beings in the form of skin and nail infections (dermatomycosis and onychomycosis).

The first ever fusarium reference can be found in the 30/40 in the URSS in a wheat infection. This infection was so bad that it was later used as a bacteriological weapon.

In cannabis plants, this disease affects mainly the roots and stems; your plants will lose strength, stop growing or flowering, and their branches or the plant in general may even begin to dry up, depending on the intensity of the attack. Fusarium wilt can affect indoor, outdoor and greenhouse grows, as well as appearing in all types of substrates; soil, coco coir, hydroponics etc.

Fusarium wilt is many cannabis growers’ nemesis because it’s one of the most aggressive pathogens, alongside botrytis. Let’s have a look at it’s main characteristics:

  • Fusarium tends to live in substrates. It lives off of decomposing organic material. Some Fusarium strains can be dangerous for cannabis plants. Some of the most common types are Fusarium Oxysporum sp., Vasinfectum, and Fusarium Oxysporum Sp. Cannabis.
  • This pathogen affects the stem, rotting roots and causing your plants to wilt; these symptoms are easily identifiable in cannabis plants.
  • Their spores are easily spread (through water, wind and nematodes) and it’s super hard to cure, which makes preventive measures necessary if you don’t want a future infection.

Fusarium Wilt and Cannabis

Fusarium wilt in cannabis plants can be caused by different types of fusarium fungi:

  • Vascular wilting is caused by Fusarium Oxysporum strains that attack the bark on your plants’ stems. This is the most common form of fusarium wilt. It can be seen as a brown stain on the stem. If you were to cut it you would be able to see the vascular damage; the stem is a different colour, turning branches brown in extreme cases.
  • Root rot is caused by Fusarium Solani. This causes general plant wilting, with drooping and falling leaves. They tend to begin wilting branch by branch, although on some occasions they may wilt entirely within a question of days.
  • Stem affliction, considered a type of plant cancer, is produced by different species: Fusarium Avenaceum, Fusarium Culmorum, Fusarium Graminearum, Fusarium Lateritium, Fusarium Sambucinum and Fusarium Sulphureum. This is easily seen, somethings showing up in intense groups of spores. This strain is rare in cannabis plants.
  • Fusarium must be treated in all types of plants, especially in areas with stagnant water such as indoor grows that use flooding systems.

Good luck poodle!

Interesting timing. Being sick fucked up me up, I think. But…might be a blessing in disguise. If the seeds I had started were doing well (still hoping), I’d probably do a half assed 4x4 cleaning, then put little ones in. Then fight spooge. Nope. Tent will be empty soon enough. Thorough cleaning in order. Oscillators cleaned and moved up a little. Clean the floor fans and Cloudline T6. Tools all cleaned and calibrated. Pots washed. Bug bomb in the shed for a clean start.
New peat/perlite next week. Need more sheet insulation for my shed while I have an empty tent.

The spray foam works pretty good. It is a little pricey but it works very well. I did the one with the screw on top it made a big difference.

Careful…he might provide all the info about Fusarium and cannabis there is. Up to today anyways, might be something new by lunch. I think @shag likes learning new stuff to share. Very generous trait to have. He’s personally helped me HUGE!

Killer tip! On my hardware store list. I can fill all the spaces in I can’t easily fit. I used 2 pt foam on boat repair successfully. My old boss used the spray in his groovy, old, poorly insulated RV. Didn’t leave room for expansion. Looked like the Flintstone’s RV. He was so pissed when we laughed. Teach him to show us peasants he was human.

About 20 years ago…was in my garage with roommates, working on something, & the subject came up… “YEAH! I can’t remember what it’s called, but I love that stuff! It’s GREAT!”

:rofl:

We reminded him the product he was thinking of is called “Great Stuff” :rofl::rofl::rofl::clap:
