How do I increase just potassium for my girls?

Hello,


I've got a potassium deficiency. Is there anything can buy from the grow store to increase the potassium in my nutrients?


Thanks,

Silver

Black Strap Molasses is high in potassium and cheaper than anything you will find at the grow store. I use it at 1Tbs/gal.
There are other options as well. Look at the N-P-K ratio... anything high in "K"

black strap makes really sweet bud, good addition during flower!!

What nutes are you using at what stage? I doubt it would be K def as most veg and flowering nutes contain more than enough.

Put up a pic so we can confirm the deficiency please. Then we can accurately help.

Not likely. Plants need far less P than most people think- due to advertisers selling snake-oil

Now you might have lock out, typically caused by either high or low pH and/or over ferting

That's exactly where I was going go with it. Just wanted a picture. Lol

greensand....high in K

I'll get pics uploaded tonight when the lights come on. I also have the Method 7 glasses so you'll be able to have a clear view of what's going on with the leaves. I'm using the H & G line feeding at the "normal" rate. Additionally, I'm using R/O water and Roots Organic Original soil. I PH my water between 6.6-6.8 and this keeps happening every cycle that I'm running. I'm really lost for what to do. This deficiency only starts to show itself around week 3 forward in flower.

Potassium hydroxide (pH up. This is the only one that will increase just potassium).

potassium nitrate

potassium sulfate

mono potassium phosphate

potassium silicate

If you want potassium, choose one.
