diagnose these.

[avant gardener]

hey gang-

what do you make of these?


these are 2 blueberries on opposite sides of the room.
there was a 3rd that exhibited the same gnarled leaves, it seems to have "outgrown" it though.

the plants look healthy otherwise. not stunted, spindly, etc. of course there's some purpleing on the petioles. it is blueberry after all.

they're in the same rdwc system as everything else that looks ok. my EC stays pretty high. 2.0 right this minute. H&G plus cal-mag is my base. i'm inclined to think it's not a deficiency.

roots are crisp and white. i flush with clear water and leeching agent every second nute change. pH is dialed at 5.8. i doubt it's an uptake issue.

i've already treated for broad mites. avid 2x at 8 day intervals. have scoped my plants under 40-100x magnification. can't see critters. infestation is possible but improbable.

ambient: 65° at night. 78° daytime.
rez: 66° always
50-60%RH.
CO2 @ 1000ppm

it's not TMV. i have negative immunoassay tests.

i run a dead rez with mineral based nutes only. i use silica. brix is around 11. no there aren't bennies. my garden is healthy without them.

have i missed some environmental issue? if so, what?
is this just a weird mutation? if so, i don't mind waiting it out.
is it something contagious? if so, i need to cull em.

any intelligent feedback is welcome.

 

[SeaMaiden]

I can't recall exactly how to do stains, but I sure would like to see a cross-section of the affected areas. I'm still leaning toward pathogen or pest.

thanks sea.

priceless.

Did they ever touch the lights? I haven't seen to much of this and imguessing not to many have is why your not getting a big response. Maybe its just a mutant. Like sea said if all is good is be inclined to says its a disease of somesort. Is it on the edge where maybe you brushed something up against it.

 

[burns1n209]

Avid is powerful stuff did you notice this before you sprayed with avid?

 

[azad]

I belived Blueberry genes did that kind of act.
Or its poss UV damage,maybe got to close to lights heat damage or bulbs need changing.

 

[junior_grower]

Blueberry is really nute sensitive. I run them at and EC of 1.2 or 800 ppm. I have found that they cannot be run with other strains that need high nute levels.

 

[Kcar]

The way I see it, they are missing something they need to grow correctly. Either it's not there, locked out, or unavailable. Couldn't say what, though. Have your been changing
your rez much? If not it might be time. Just my 2c. Good Luck!

 

[Granger2]

Avant,
I think Azad hit it. Blueberry, especially DJ's, is known for leaf deformities. I can't really tell from the photos iffin it is or iffin it ain't something else. Doesn't look like nute burn, deficiency, lock out, pH, or too close to lites. The other one's growing out of it is a good sign that it's genetic leaf deformity. Good luck. -granger

 

[avant gardener]

thanks for the input.

definitely not too close to the lights.
about 18 inches here.
not much less than a foot anywhere else.

bulbs are a week old.

nutes get changed same day every week.

avid happened 6 weeks ago, right after they threw roots. the moms haven't expressed this deformity. anyway abamectin is only minimally (if at all) phytotoxic and mutagenic.

on the edge? yeah. everything is. otherwise i couldn't work on them.
do i brush up against them? with a pant leg, sure. that's not what you meant though.
what did you mean anyway?

as for the EC, the aren't exhibiting any signs of burn. everything else is lush.
i do small test runs of things before i do them in the buckets. that let's me get a feel for how they grow, what they like, and what stressors they'll tolerate. if i'm going to get surprised, i'd rather have it happen with a handful of 3 gal pots in the aisles than in a recirculating system in a room that costs more to operate than my mortgage payment. in any case, 2.6-2.8 was where they really started to cook. 2.0-2.2 seemed to be the sweet spot, and that was in soilless. they can generally handle more in water. in fairness, a decent chunk of those dissolved solids are sugars and silicate. that would be a hefty dose of NPK.

so yeah, i'm going to run with mutation as a working hypothesis and keep an eye on them. long as they're not fucking up the neighborhood, i'm inclined to let them do their thing. hell, who knows? maybe they'll exhibit some new favorable trait like finishing in 4 weeks or trimming themselves.

I have seen this many times in the blue line. I also got it with Magenta99(PCK X C99). Its not a pest or pathogen. Some kind of mutation in the genetics..

 

[Rob Deck]

Yes, I agree with the previous two posts about being in the blueberry genetics.

I had a blue satellite #2.2 which was a heavily leaning blueberry mutation, as you can see:






It had crinkly leaves and purple undersides just like yours, enjoy!

 

[SeaMaiden]

No shit, genetics? Well, there it is, if it's been seen before and it's common with this line, there it is.

 

[Hammerhead]

my pics look the same. Nothing can be done some will grow out of it depending on severity. I had a few that where on the extreme side. They grew but where just not what I like to see in my garden. the mutation never went away.It effected the plants vigor and yield so they got tossed..

 

[avant gardener]

huh.
bummer about yield, but it's only two, so i'll leave them. if they start to lag, they'll get swallowed up on the trellises anyway, so no huge loss.

that's the biggest shortfall of recirc though. since everything needs to get flushed at once, i can't just switch things out at will.

thanks folks!

 

[c-ray]

on those I like to trim away the parts of the plant that are most mutated and let the plant focus it's energy on the least mutated parts.. they usually grow out of it but it can take a while

 

[avant gardener]

ok bb experts.
got another one.

you folks seen this before?

she's perfectly healthy looking otherwise. one isolated case. and it's not even the whole plant. just this pair of clusters. observe:

thanks in advance.

 

[avant gardener]

bump bump

 

[Hammerhead]

Blueberry genetics can through out a lot of mutations..I have seen the 2 tone color leaves before

How did variegation occur in houseplants? Was Ficus benjamina always "available" in a variegated or non-variegated form? How about pothos, or philodendron? I find myself wondering if this is always the price of domestication, though I'm only familiar with the a-melanistic or white areas (think of dogs, cows, horses, cats, and that Russian fox breeding facility and how they ruined the foxes for fur, but learned so much more by making one simple choice--breed only those foxes that were less aggressive) in animals, not in plants. But it seems to me that it could happen.

In fact, it's now occurred with captive-bred and raised anemone fishes, mostly Amphiprion percula and A. occellaris from what I've seen. They're calling them "platinum" and stuff like that, but all it really is is a color morph that's unnatural.
