Wind burn / heat stress or budrot?

[goDsnataS]

Woke up this morning to find my box running a little hot (86f). I've got two phenos of purple wreck going, and one of the urkle phenos nearest the oscillating fan has some sugar leaves that look like they're drying out and dying.


The thing is, this happened to one of my urkles last run, and it turned out to be budrot due to high humidity and a circulation dead spot. This run I've got my humidity at 50% and plenty of airflow, so the last thing I expect is budrot. I'm hoping that its a minor problem due to the oscillating fan blowing the 86 degree air on the cola all night.

I've moved the plant further from the fan and turned up the ac; should that be fine, or should I harvest this plant early? I planned on giving it another week or two.

Hope you have been examining the trichrome development. The changing color of your fan leaves and some sugar leaves to purple is letting you know your pretty close to harvest. I don't see the slight opaque grey silouette from your picture anywhere on your top cola so at the time of your photo bud mold has not occured.

you did good by turning up the a/c and moving the fan

Thanks for the responses.

The cola with the budrot last round never showed any gray or soft, squishy parts. It started with the sugar leaves drying, hardening, and twisting, followed by the cola drying, hardening, and browning. When I realized there was a problem, I chopped the cola and opened it to find black mold in the center.

By the way, I'm on day 49 of 12/12, and 44 since first signs of flowering.

I dont think a fan caused the deficiencies, major P def. Put the fan back on or it will mold and next grow have the waterings and feeds at 6.5 PH to avoid lockout in flowering.

 

[*BUDS]

[h=3]Phosphorus[/h]Phosphorus is a component of certain enzymes and proteins, adenosine triphosphate (ATP), ribonucleic acids (RNA), deoxyribonucleic acids (DNA) and phytin. ATP is involved in various energy transfer reactions, and RNA and DNA are components of genetic information.
Phosphorus (P) deficiency
Figure 11 is severe phosphorus (P) deficiency during flowering. Fan leaves are dark green or red/purple, and may turn yellow. Leaves may curl under, go brown and die. Small-formed buds are another main symptom.
Phosphorus deficiencies exhibit slow growing, weak and stunted plants with dark green or purple pigmentation in older leaves and stems.
Some deficiency during flowering is normal, but too much shouldn't be tolerated. Red petioles and stems are a normal, genetic characteristic for many varieties, plus it can also be a co-symptom of N, K, and Mg-deficiencies, so red stems are not a foolproof sign of P-deficiency. Too much P can lead to iron deficiency.
Purpling: accumulation of anthocyanin pigments; causes an overall dark green color with a purple, red, or blue tint, and is the common sign of phosphate deficiency. Some plant species and varieties respond to phosphate deficiency by yellowing instead of purpling. Purpling is natural to some healthy ornamentals.

Yours is similar.

No helpful advice, just wanted to say despite the leaves shes gorgeous

I don't think it's a deficiency as all other leaves on this, and the other plants, are fine. My purple urkle phenos did the same last round.



I use the full roots organic lineup including hp2, and hpk, in roots organic soil, and ph to 6.3 in early flower, 6.5 in late using earth juice natural up. The fan is still on, I just moved the plant one pot over.

My only concern are the 3 small single leaves in the cola that have begun to dry, harden, and twist... they were not like that when the lights came on last night. That was the first symptom of my experience with bud rot last round.

A clear indicator for the spread of Botrytis is the yellowing and wilting of a bud leaf in the main cola.

They give a few tips; one is to remove a bud from the cola to inspect and provide circulation. I'm gonna give that a try when the lights come on tonight.

You gotta poke around a bit. Inspect the shit out of that bud top and try to get a look at the stem. If it's mold, and the leaf turns/dies, then the mold has already got a hold of things and is rotting from the stem out. Pull/push the buds apart until you see the stem. If it looks fine, then you're good to go.

 

[goDsnataS]

Yep. Brown mold in the center.

Fuck.

Oh well... everything else looks good. I really thought 50% humidity and full circulation would solve it. The only thing I can think of is that I was without ac about three or four weeks ago and humidity was high. I guess it set in then.

Heres a shot I just took of a trainwreck pheno-



I think I'm gonna cut the urkles down next weekend, and the tw's in two weeks.

 

[tusseltussel]

sorry to hear it hope you can save some goodnugs off of her

 

[goDsnataS]

Yeah, I'm sure it was just the top nug. Last round I lost one cola of the same pheno; I didn't address it until it was totally brown and crispy, but the other nugs and plants were not infected. This time I caught it early.

 

[tusseltussel]

I thought I remembered something about spraying the mold with h202 to disolve the badies. but not sure, might do a search for it, if you cought it early enough than might be able to chop it spray it and hang it to dry

I read somewhere that freezing would sterilize it, so I bagged it and put it in the freezer. What do you guys think about using it for a green dragon tincture? Would the heat and alcohol be enough to make it safe?
