Curling Leaves - Broad Mites or something else? - With Pics

Hi Everyone.

I am currently flowering three plants - OUTDOORS - all are about 10-14 days since they showed sex and went into flowering I guess.

Out of the three, One plant is showing major leaf curling.

I am battling mites for sure

Also to note: during the last 8 days I have watered 2 times, fed both times, and probably fed too much grow nutrient during these last two feeds. (This was as per manufacturer instructions)

As well as going heavy with the Grow nutrient, I also added some calcium during the last feed .Also did a foilar feed of liquid seaweed.

Please help me identify the problem.

If its broad mites then I might reluctantly get some floramite. Been treating with neem so far.

Some pics here and some more info is also noted down after the pics.



















- Coco/Perlite/Vermiculite mixture in pots.

- Mandala seeds - safari mix.

- She is now flowering , roughly 10-14 days in.

- General Hydroponics 3 Part.

- Feeding When pots feel light / emptyish, giving nutrients with every watering.

- Switched to bloom feed 10 days ago. Manufacturer instructions recommend higher grow nuterient for first two weeks of flowering though, which is what i did.

- Last feed was 900 PPM - including some added calcium nitrate.

- Last watering was 30 hours ago - after which the problem increased a bit.

- During my last feed I added calcium nitrate and also foilar fed with liquid seaweed for the first time.

- Flushed only once about 3 weeks back.

- Pests - spider mites and leaf miners, god knows what else

Nitrogen claw. You cant over feed if you have a ppm meter.

How do you know spider mites? Is that plant next to the infected?

Well what were your ppm goimg into the problem?

I checked the PPM - it was about 750-800 - I didn't think that was high. I think I just put too much nitrogen as opposed to more bloom nutes in the mix.

Well Check this thread I posted about a week back.

https://www.rollitup.org/t/outdoor-leaf-miners-spider-mites.886613/

This plant is one out of three, they were all facing the mites problem. So far I have been giving it neem oil sprays to control the problem. But now I have managed to source a few other things which are supposed to work -

1. Floramite
2. Spinosad 45% EC made by Bayer
3. Azadirachtin (the main thing in Azamax)
4. Hirsutella Thompsonii - Just learnt about this stuff today!
5. Pyretherum oil 2% concentrate
6. Other bio miticides available in my country

Since they are already about 10-15 days into flower, I am reluctant to use hard chemicals (floramite).

Will try the other organic solutions - starting with Hirsutella Thompsonii in a few days. Anybody here has experience with this stuff?

Thought I should add - the plant is looking better today! The leaves are looking bigger/better, although the clawing is still very much there. I flushed them just now, the PPM of the runoff from all three plants is about 400 PPM now.

Will see how they drink over the next day or two and plan next feed at half strength Bloom Nutes.

Another observation today on one of the other plants:

What does this look like now?

There isn't a link for a thread? Because the first imo didn't look like any bugs what so ever, neither does that last plant

Flushing can make matters worse ....

Just added the link once more.

In my first post of this thread, all the pics are of the same plant

The pic I posted today of a spotted leaf is from the second plant. If you zoom into this pic from today, you will be able to see the white spots that were caused by mite damage.

Also, if you can see my other thread about the bugs - you will be able to see the spider mite and leaf miner damage! Link here - https://www.rollitup.org/t/outdoor-leaf-miners-spider-mites.886613

Oh well, too late now mate! I flushed them a bit just an hour ago, more than flushing i just watered them heavily with plain water until the runoff PPM was close to 400.

Saved it, thanks.

I have one question though - How does one over-water with coco/perlite mediums that have such good drainage?
I thought the whole point of such mediums is that they hold just the right amount of water in them?

Also, Wouldnt hempy buckets be considered over watering, since the roots are always submerged in water and there is no pump or bubbles to oxygenate the rootzone?

Was able to get these pics - mites .. and what else?

Bottom looks like russet mites, I used nuke em before !!

First is aphids, check out the link and read up. Get clean, like I said nuke em did it for me

http://www.growweedeasy.com/bugs-pests-symptoms-marijuana-grow

tops looks to be the dreaded BM, yellowish clear bodies fuckers are only viewable with like a 20x or so scope right? Causing clawing like the pic below? That was a confirmed BM attack, first time I encountered them… Forbid 4A'd those motherfuckers!!

Man Nuke-em and Forbid as such are not available in my country, and neither is forbid.

I am already 15-20 days into flower so reluctant to use harsh toxic chemicals.

I have been giving them neem oil sprays , but I figured that alone won't be enough.

Ive sourced a few organic/biological insecticides - all these things can be used right up to a week or so before flower - but I need to reach that point first. These are the things I'm getting:-

1. Spinosad 45% EC made by Bayer
2. Azadirachtin (the main thing in Azamax)
3. Hirsutella Thompsonii based bio inecticide
4. Beauveria bassiana based bio insecticides
5. Verticillium lecanii based bio insecticides

6. Pyretherum Oil - Not sure if I will get this !

Im gonna bombard these fuckers with a different weapon every 3-4 days using the top 5 on rotation.

Has anybody got experience with these fungus based bio insecticides? I've heard they are quite effective and safe of course

Thanks for the input guys, really appreciate it.

20 days into flower you're not going to kill them… Nuke em is the only organic method I know that has worked for folks in veg but could be used in flower if you could get it, but thats like a 1 month process. You have 2 options, let em go or start over…

Remove all the affected leafs or ones you think might be and just let it grow and hope its a 55 day finisher. There are organic safe to use products in flower, but Broadmites are just a different beast all together...

Exactly - not going to kill them - I have no other MJ plants going so might as well try and save them.

Starting over is not possible right now, winter is coming soon and will be too cold for plants to survive.

Will let them go and hope for the best.
