Strange leave damage. Random and steady increase.

[AtLantis]

Hi guys.

We´ve got "skunk #1" growing from clones. Day 24 flowering. Roughly a week ago we started noticing these leaf damages. One branch had all the leaves damaged. Another had just a few leaves damaged and others just sections of the leaves. Have you any Idea of what this might be. Have gone through alot of web search and found no similar looking damage to the leaves.
The photos are very good so please take a look and please share knowledge and experience.
All help is appreciated.

My thoughts are maby root rot :/?

More info:

Substrate : 100% coco
Nutes: H3ad´s modified lucas formula+atazyme+rootstim+diamond nectar
Temps: Very well controlled 24°, Good humidity and nice air circulation.
Lights: 400w HPS

Could be broad mite damage. Check undersides of leaves with 100X scope to confirm. Cut a couple of the worst leaves off and get them under a scope. It's the only way to see them.

Some leaves are slightly twisted which could indicate a ph problem also the tightly bunched leaves and purple stems could indicate that it's too cold maybe not your room temp but maybe the water or soil. Try not watering until the coco becomes completely dry.

Doesnt look like a pH/nute problem to me because some leaves above/under the affected leaves look perfectly fine. A lockout/burn/etc will start affect leaves gradually not randomly.
Like Retro said check for pests or infection.
Check also for offgassing.

Thank you Guys for replying so quickly!

And I think you Nailed it! Right on the head ! (BROAD MITES)

The third picture in that link looks horribly similar to what we are facing.

We are going out wright now to buy a scope.

I have dealt with spider mites before and they are a nightmare imo.

How do we deal with the Broad Mites? Shoud we gass them with Co2 ?

We are starting to have buds so we´d preferred not to use pesticide, but if thats the way then so be it ! =(

Again thanks for your quick and efficient replies

Try Neem oil. Have had great success with it.

 

[russjcan]

neem oil will ruin your flowers. Max the room with co2. I'm outdoor and use ladybugs every week.

True it will. Sorry Atlantis, I should have clarified my post. I use a small paint brush to pain the under side of leaves. I don't do a large grow so its not a problem for me.

Not Broad mites imho

You must confirm with scope. If you see eggs under leaves, you have them. Pictures look like broad mites. You cannot use pesticides in flower. Your options are heat treatment or predator mites. See the broad mite thread if you confirm mites with a scope. CO2 is another option, but I have never tried it.

cal mag for the win.


My heavy chem strains exp chem 91 does this when in need of some cal mag. looks like what it is to me.


its not broad mites or you would have no pistils on your plant.

Exactly what I was thinking!

So I have bought a 30x scope. and this is what I see.(Couldn´t find 100x)

All over the underside of the leaves there are small balls. Most crowded under the damaged parts of the leaves.
Resembling trichomes, similar size but no stalks just the head.
Almost all of them milky or white but few are clear.
I see nothing moving and no sign of Broad mites.(I will keep on looking)
I read somewhere that the broad mites eggs are lined up. That seems not to be the case with these balls for they are all over the surface.

Do I need a stronger scope (100x) to see the eggs or mites?

If these balls I am seeing are eggs, are there any tell tale signs i can spot to confirm that they are?


This community is serving me well. I look forward to paying you back.

Thank you very much

Let me know what you determine the problem is here. I have ended up with a room full of plants looking just like this come early flower, they never finish for me and usually hermie, some dead pistils here and there (by no means a lot, as a % maybe 10).

Has to be either broad or cyclamen mites, or pH lockout/nutrient deficiency. Unfortunately I am leaning toward a pest problem. Have not attempted a grow in 6 months. My last several have ended in total failure, which certainly suggests a constant pest and not nutrient/pH issues. I always checked pH and EC when my problems were happening.

i dont see bug damage the little balls could be broken tric heads...

maybe the pests are in your rootball

Ding Ding! We have a winner .

OP your plant is suffering from mag def. cal/mag or Epsom salts @ 1 teaspoon per gal. should fix her right up. The chem lines are notorious for this, also seen it in a few of dj shorts strains.

We have been feeding with H3ad´s Modified Lucas formula from the start.
Wich has 1 g Epsom Salt per Gallon.

30X not enough to see broad mites, if you had them.
Not saying you have them, just that you have some of the symptoms: blistered & twisting leaves. Only one possibility, but you need a 100X to confirm. It very well could be something else, but you said you were using epsom salts for the cal mag. It sounds like what you are seeing is just trichomes.

 

[FunkJungle]

You seem to have some sort of nute lockout. Have you checked your roots, and calibrated your ph pen?
