Potassium Deficiency ?

Hey guys Im mid flower with banana daddy auto in coco in autopots. They have been getting huge and drinking a whole reservoir every 3-4 days

Ec is running 1.9-1.92

Canna ab @7ml/ gallon
Cal mag @ 2ml/gallon
Epsom salt @ 1/8 tbsp gallon
Canna Pk@ 2ml/ gallon

I know the pk is low but I had read a different tek of using all thru flower at lowe doses


I just upped pk to 6ml a gallon, right in line with recommendations

Was I right?

In my opinion, that looks like potassium, because of what’s happening to the leaf margins.

It did in fact end up being potassium. This plant grew nugz the size of my forearms and Im built like the Rock. Theyre autos and ate basically full strength nutes. Photontek lights are apparently legit

This was happening to mine I think I've stopped now, got a high potassium feed it's 6-6-12.

Hell yea! Glad you got it sorted. First time I encountered this I thought it was burn and cut back on nutes to disatrous result. Its taken me a while to suss out the subtleties of this plant. Im not a natural gardener and the deficiency and problems can kind of overlap and resemble eachother a lot.

That's a pretty common error. Glad to see ya identified the problem and correcting it. A nice even dose of nutrients is needed. Your in flower so npk is pretty important. Calcium and magnesium needs get higher in flower as well.

I was panicking at first but I suppose it only helped me tune in to the plant more and it's my first grow so we'll see if I haven't hurt her. Yea they can be confusing now I know, it's been a great learning curve, hopefully I'll avoid it in the future.

Oh, believe me. There will be more errors along the way. It's how you attack them that counts. Good job dude. It's cool seeing a new grower identity his own issue. Now you can pass on that info to the next guy. With confidence because you experienced it yourself.

I'm sure there will. Thanks, I'm very enthusiastic about it all. And I'll be sure to share my wisdom.

This is the feed I'm giving her now.
