Strange Burn

[nomaad]

WTF????!!!!

Can anybody tell me what this is? to me it looks like a contact burn rather some kind of nute burn that started in the root system.

My first guess would have to be the Kaligreen which was applied yesterday evening. This was found on one side of one single Tahoe OG plant.

I have the Sherpa outside now making up a batch of kali green. We are going to take some fan leaves and soak them, then leave them in the sun. I am thinking that the morning dew formed and in the drops it concentrated the kaligreen, causing the burn...

dunno. any ideas are appreciated. I'll start a thread as that usually gets more immediate attention to my more emergent issues.

Not only are the leaves affected, but some of the hairs as well have been burnt this orange color.

Can be very hard to tell you when it comes to the outdoor...

I have many girls growing up under same conditions....and a very few of them looks sick...

thanks paddi. anybody else?

hmm...the way it's on the margins makes me think it's not from the spray, usually you have more of spotted deal w/ the droplets. i dunno...maybe potassium def? perhaps some test foliar applications might be in order. the way the bud got toasty sure looks like heat damage though.

 

[nomaad]

no way its a deficiency. last night the plants were not like this. this afternoon they are.

we did a test on some leaves and put them in the sun. it was late in the day so we did not see the full effect, but there was noticeable burning with a higher concentration...

the balistics pattern is that of spray. Like its all localized on one quarter of the plant except for one other cola and the one directly below it about 90 degrees around the plant...

my most plausible theory is that there was an undisolved chunk that got lodged in the sprayer neck. When the Sherpa cleaned it (as you have to do periodically- or change the diffuser tip) he may have broken up the chunk, smeared it against the wall of the tip... so then the next 10 seconds of spraying (this is what the pattern looks like) has a very highly concentrated potassium bicarb dose in it... which has been reported to burn ganja.

I am hoping for a response from DSTokerMD who reported burn in his first greencure applications.

i have seen dirty plants with buildup in a similar location on the tips of the leaves like this... that's what makes me think differently from the above quote.

dunno, man... we'll see if any more of this shows up.

Nomaad is this the only bud that shows these signs on the plant? If it is, i would say it's the spray...Did you use 3/4 tablespoon per gallon? What's the recommended dose of Kgreen per gallon? might want to back it off to a 1/2 tablespoon...maybe try it w/out the sticker too

If it's more widespread i'd say it's a lockout issue...you ph your water right? what do you use for up and down? GH, Advanced, other?

 

[nomaad]

only one small part of one plant. i really think what I wrote above is the explanation for how it happened.

Spraying at night. I have made the same mistake too. Next year get an atomizer. They are the bee's knees. Early morning is the time to spray. Pump sprayers are much more likely to do this kind of burn.

 

[nomaad]

what kind of atomizer do you use, holmes?

 

[3rd I]

Must have missed that while i was typing...possible

 

[snafu421]

wow

 

[nomaad]

Anybody have an opinion as to what I should do with the afflicted colas? Cut em off? Let em go? Think this burn could lead to lowered mold resistance or anything like that?

 

[nomaad]

get them posts up, snafu... you'll get an avatar yet.

 

[humboldtlocal]

I don't know the name of the atomizer it was around $300. One of the best investments I ever made. I have two of em. I would just leave those branches be. Some of those burnt leaves might die so pull them off when they do but that bud should finish up fine. It might not develop like the rest but it will produce something. Of course if it gets weird, hack it.

Definitely leave them on and let them grow, they will bounce back. Sorry about the damage.

I've been using a product called Bi-carb and like the Kaligreen it is a micro encapsulated potassium bicarb product which I use with a sticker spreader and I've been very happy with the results so far. I'm fighting Powdery Mildew and I can tell that I have a handle on it now. That is a relative term though and the PM is still in the garden so I must battle it every day.

Good Luck

 

[nomaad]

I think I caught my PM on about day 1 and have eradicated it with the Kaligreen... I don't want to be afraid of this product!

 

[Ipsissimus]

my bad, I was thinking about light burn I've experienced from small droplets.

only one small part of one plant

oh nice! if it's just the hairs on the bud, leave it, otherwise snip it.

nomaad- i own an atomister. its the best foliar product... period... it breaks down ever particle of moisture into a 20 micron size and with a motor shoots the pressureized spray out about 6 -10 feet.... WOW im glad i held off on the kaligreen tonight... um what wetting agent did you use?? I went to pv today, got my 5lb bag for 60 dollars, and picked up a yucca sticker spreader... but damn... those results are scary... we need fisher to chime in here as he seems to have no issues with it...

Also, when i spotted the pm, i used organicide, and i have no burn, and as of now no showing pm... we will c tho... hope it works out man. im gonna hold off for a sec til we get this figured out....
