Greenhouse Leaf problems ! Southern Hemisphere

[Masterbear]

Good day fellow tokers!

I have a slight problem and not sure yet what it is but I'm leaning I. The direction of heat stress. I have a 15x5m2 greenhouse inside are about 30 females and all have started showing gender. They are huge and growing well but my leaves in top nodes are coming out deformed and discoloured. They look very wimpy this is just one example but a few look affected like this. Any ideas what this could be? They all planted in the same soil and received plenty of rain this time of year. Plenty of size
And flowers are lookin go great so far.

Please help!

Could it be a Cal/mag deficiency?

Here is another look at the tops it's only one or two tress now that seem affected. Someone said it could be board mite is that right? Kills the pistils browning them and they live in creases of leaves killing them making them curl upward. For now I have choppe off entire branch of the one to see if it helps the remainder of the lady. It's flowering for about 2 weeks now and the pistils keep dying. Any method to rid the board mite? Some of the fire in the rest of the greenhouse coming on nicely!

old fashioned 'nute burn'

flush with 3 times the pot volume with air temp ph'ed water

allow to recover in dim light 8 hours or better drain overnite

good luck

They get no nutes at the moment besides organic seagro, cannot be a nute burn? Ever encountered broad mites?

 

[vostok]

not rocket science here

nutes are added at the factory

SEAGRO® Professional Organic Grower Mix

Made from Canadian sphagnum peat moss composted with ocean fish and cattle manure,

resulting in a nutrient rich compost mix which acts as a natural fertilizer,

potting medium and excellent soil conditioner.

Honestly it doesn't look like any nute burn I've ever seen. Looks more like pH burn, but so extreme I've not encountered it personally. And is it the whole plant doing that or just the top? OP what is your pH? May be some fungal issue none of us have seen because you're in the southern hemisphere.

 

[Masterbear]

Correct it is in the Southern Hemisphere which makes this much harder than anticipated. Didn't use seagro compost mix used an organic medium made of bark and peat no nutes added with third vermiculite. The seagro I'm talking about cannot nute burn your plant it is organic made from seaweed. As for @plantcity yes it Ian mostly the tops and only one or two nodes of the plant. It's strange. Maybe it's a deficiency but I know we had board mite on one of our indoor so it's likely

u growing the sour d again this yr? never had russet or broad mites but the damage I see on your plants looks very simaler

i'd be checking VERY carefully for broad or russet mites if i was you.
i see no claw from overfeeding, i see no tip burn from over feeding, i see no random white patches from ph swings....
so what does that leave?

Thumper my man we have some sour diesel running at the moment plus I pulled some Amelia Haze (Atomic Haze x Amnesia haze) she is looking stunning already. The sour diesel is off to a slow start this year but slowly catching up. The rest are coming along even nicer! Some LA Confidential

I agree with you Roger, flip man we have a litchi tree next door and those are always infested with worms and all sorts of bugs. We had an indoor plant that look sick first that's how we knew we vegged them outdoor for less than a month. Any organic way to rid them or should I chop branches

broad mites are tough to get rid of, if you have a big garden sometimes you're safer just burning that plant.
mighty wash is supposed to be good, and not insanely expensive. Avid is the gold standard apparently, and cost almost 100 bucks for an 8 ounce bottle. i don't like the idea of using either once a plant has started to flower, although mighty wash says its safe to use in flower.
i haven't had them myself, but if i ever do, i plan to try spinosad as both a spray and a soil drench before i try anything like mighty wash or avid

Gee thanks Roger that's mighty helpful. I will make sure we get some mighty wash. I also don't like using anything after flower has started it's like the ugly duckling always, the tainted kush- no one wants that not even you
