leaves rotting

Hey guys what do you think is wrong with my plant? It's not nitrogen because first it doesn't look like it and I've treated it for it and it didn't help.

What medium are you using? What nutrients? What's the pH of your nutrient/water mixture that you're feeding the plants?

You may as well add lights in use, temperature, humidity etc while you're at it.

Looks like a phosphorus defiency to me.

Have had similar looking plants in the past

I agree.

Looks like a Magnesium/and or Calcium deficiency to me.
Splotches on the leaves are a tell tail sign. Can seemingly mimic a Nitrogen Deficiency.

Hey guys, I'm not trying to be a Debbie Downer, but I sure hope this plant has been harvested by now. If she's still flowering after 6 years she must be a beast, lol.

Kidding guys. I can still learn from it.

Can’t be both together so youd need to Pick one because too much of one can antagonise the other.

i know it’s 6 years old but felt it necessary to correct your Ca and or Mg as it can only be Ca or Mg.

But never both.

so if this is your answer you’ll need to think carefully because the solution could cause an antagonistic response from the other.

another reason why I hate CALMAG products.

it’s a sledgehammer approach as it adds both and if your issue is caused by an abundance of one it won’t help the issue.

I dont use cal/mag myself. I use Epsom salts. Most likely Mg problem.

I use Calcium Nitrate for Calcium source, as well as Nitrogen. 15.5-0-0
I use 4-20-39 as base
Epsom Salts
