Dark Spots on Leaves, deficiency, fungus? Help!

Hey fellow growers,

This is a new strain that I added to my garden so I am unfamiliar with it but I am getting some weird spots on the leaves.

Strain is GDP
indoor
under cMH
watered with buddha bloom nutrients and mammoth p and some worm casting teas
using filter water with pH range between 6-8
One circulating fan and one exhaust fan
I currently have added ladybugs into the garden to protect from anything from spreading

Thanks for any help guys! sorryy for the low quality photo I hope it helps
I have looked under 100x scope and nothing seems to be moving around in there.

@Niala will probably know.

I think you have an excess of iron. What are you feeding, and how often?

It’s buddha bloom and I feed it nutrients every other watering

Ideally your watering/feeding pH should be 6.4-6.5 for soil 6.2-6.8 is acceptable but above or below that you’re probably going to run into some problems.
What’s the pH of your runoff?

I have not tested my runoff. I will do once I get home and let you know. I am in soil.

Don’t water if it’s not time yet. Just test it next time.

Also, a pic of the whole plant when you get home.

Can do a slurry test on soil if it isn’t watering time

Thanks for the tag, @blackthumbbetty

It looks like calcium deficiency or iron excess or the beginning of leaf septoria… Are your leaves are bronze in color, if so, it’s probably iron excess like @raustin suggested… It also can be in the genetic of GDP, it’s an early 3 finger leave and just trying to reach it’s purple destiny… Lol :stuck_out_tongue_winking_eye: :sunglasses:

Also, did you foliar spray and let tiny water bubbles act like tiny lenses, CMH, produce some UV’s and generally have an extended spectrum’ till the IR too, so it’s also possible that’s the culprit, you’ll see if the dark spots turned in necrosis yellow spots in a few days… :stuck_out_tongue_winking_eye: :sunglasses:

Without a picture with more of natural light, more illumination, it’s hard to say… Use a flash or take your picture outside, at noon… Video captions outdoor or indoor with sufficient light, can , if you film with the sun or light behind your captions, can be an awesome way to do it, if you have a YouTube channel and post it here…

Knowing EC\PPM in and out will also be useful as a picture of the whole plant like @raustin suggested,. @AlmightyHAM

And a slurry test, like @Smokin_ernie suggestion is a great idea too and keep a register of your runoff or slurry test for future reference to know if your plant is “eating”…

I think this plant has an excess of iron. You should do a flush and then feed.

Once I flush should these spots go away?

The spots will probably not go away. The leaves are already damaged and won’t recover. Look at the new growth to see if the plant is recovering.
