Help a beginner out

[Tommy626]

I got black spots on my fan leaves. Foliar spray a few times and humidity got high over night. What can I do?

 

[threatco]

Nothing to be done now. The leaves will keep their scars. But just stop foliar spraying.

 

[Tommy626]

It’s spreading everywhere on the plant. Multiplying everyday

Even after stopping the spraying?

You may need to lower the light intensity until they recover from the stress.

Have you looked under the leaves? Under a microscope? There are many kinds of mites that are too small to see with the naked eye. I “thought” my leaf damage was light related but I took the leaves too the microscope and saw russet mites and larva. They destroyed one of my plants but the other two were saved and no more pests.

what is your medium? what are you feeding? which fan leaves showed damage first, upper or lower? take a pic of whole plant

The medium is a peat mixture! I know that was a mistake looking back on it. My ph was low in all the peat pots. Like below 5.5. As for feed I’m giving them RAW powdered bloom small amount of cal mag and recharge.

There is no bugs or any evidence of bugs with a x50-1000 loop

I’m feeling like chopping it all. Cleaning thoroughly and starting all over. This totally knocked the wind out of me

 

[threatco]

I'm not sure. But having too low ph and locking out Ca Mg an P could be the cause. The fix may be PH up.

Give it a splash of cal/mag, dots look a like calcium def.

 

[Tommy626]

They’re everywhere on the plant

 

[Tommy626]

Is it possible a fungal issue?seems to be getting quite aggressive

 

[threatco]

It looks like Calcium deficiency. But you have added CalMag all ready So it's probably not able to absorb it in the acidic soil.

looks like fungus to me

Why are you still spraying the plants?

• Rule #1 Never spray a healthy plant

One level tablespoon baking soda (& a few drops of gently dish soap) into one gallon of water, spray both sides of the leaf asap, spray heavy!

If it is a fungus the baking soda will stop it instantly and then you will know, regardless it won't hurt anything;

Recommend liquid copper Fungicide and in about three or four applications it will hopefully eliminate the fungus, also increase the airflow on the floor asap, good luck

 

[Beachwalker]

Brown spot w/ black ring = septoria

 

[chemistry]

In pots I like a ph of 6.2, or you'll wind up with a calcium def, which is normally followed by a mag def, hence they come mixed in the same bottle, you need to flush your pots through with a nuit solution with a ph of 6.2 for a win, and watch them bounce back, don't know how many ppm's your feeding, so cant offer any advise on that, but that's what I would do, 5.5 is low, I only went to 5.8 in DWC, and that was tight if it dropped any further.

 

[threatco]

I'm all in on the fungus train now.

Will this spread to all the plants in the tent?
