Browning on lower leaves DWC TNT Kush

[Buyakasha]

The spotting has been getting progressively worse, at first i thought it was a nute deficiency because i was using 1/4 of the suggested strength so i bumped it up to half strength, but that caused some browning of the roots so i went back to 1/4 strength.

Looks pretty similar to whats happening to my ak47, did you notice if the stem the brownish leaves are on has a red/brown color to it? mine does

Not sure on your exact situation, and honestly someone correct me if I am wrong. But I have heard that if the lower leaves are starting to yellow/die but have a red-ish tint to them, then it may be a simple potassium deficiency. Not sure if you've considered this?

What nutes are you using? If any. I just recently went through a problem such as yours and upped my potassium (via organic nutes, that's all I ever will suggest personally). Cleared up rather quickly.

I'm using roots organic 707 soil, RO buddha grow and bloom for nutes. The plants are 5 weeks old, 5 days into flowering.
