Hi this is my second grow I have 2 northern lights and Just on one plant I have brown spots. I use calmac every feed so not sure if it’s calcium definition or not
My ph is always around 6.2 on coco and perlite I’m about 7 weeks into flower
thanks

IMO It does look like a Calcium deficiency to me as well. You can do a little test on a lower branch. Take it and kind of squeeze it and bend it not hard but enough if you can tell if it's brittle and Hollow.

I use calmac every time I water, so I flushed it there with Just ph water and I will give it more calmag shortly thanks

Next grow a good trick is to put your Coco in a smart pot then the smart pot into a 5 gallon bucket do a full dose of Cal Mag with water and soak the Coco. Then just lift the smart pot out of the 5 gallon bucket and let it drain. It will absorb much more cal/mag. It should be easier to maintain your levels throughout the grow with this trick.

They look like spider mites to me. All those spots are where the spiders bit underneath your leaf. So, look under the leaves.

This is what I was thinking too

Hey John boy, I think 147 is right ,mites an they are hell to get rid of ,if that's the problem, an I think it is.

 

[John boy]

[John boy]

D.a.a.s.69/ so I have disappearing mites in my grow room? I think I would see them. But thanks for the imput

 

[Canuck147]

Those little yellow things are spider mites. Shake it all you want, they won't come off that way.

 

[Canuck147]

We are both right. Look up on the GWE to get rid of them.

 

[John boy]

So how can’t I see them?

 

[D.A.A.S.69]

You better be getting rid of em., they are hard to get rid of, they will be all in your buds, if they aint already??
Read Nebulas articles about them, .

If they are mites you will know for sure soon enough. They multiply quickly and can easily overrun a grow. If you are not seeing any you could still try to do some preventitive/eradication methods. A organic mite killer/mold killer.

To be honest ive never first hand seen mite damage/infestation. But these guys are pretty good at their stuff. I would not just dismiss what they are saying. Do you have a magnifying glass. Maybe get a up close look. Also place a few strips of duct tape sticky side up under your plants laying on the medium. If they are there some should stick to the tape.
