Is this a Potassium deficiency?

I wouldn't give them anything especially molasses unless u want horrible tasting dope. No harm intended last poster. Those plants are almost done give them straight water and strip yellow leaves.

The first time with my FFOF soil I used Earth Juice. So I made teas with it for each feeding. I always added a small handful of EWC and some Earth Juice Hi Brix, which is basically molasses, to each batch, and bubbled for a couple days.

My buds were super flavorful, but they all had a similar taste, that almost tasted a little like molasses. I knew that sounded kinda crazy, so I searched around and found people talking about how guano can "mango" or "sweeten" buds, so I thought maybe that was it. I even made a thread on RIU. https://www.rollitup.org/t/does-guano-really-mango-or-sweeten-buds.1027200/

But that strange molasses type taste definitely wasn't the guano. Guano is one of my favorite amendments. And although I think it might add flavor, it definitely wasn't the cause of that strange aftertaste. It had to be the molasses at every feeding.

Don't get me wrong. I'm not against molasses at all. I usually add some when I'm adding microbes, just to give them a boost. But if I want to add K, I use Langbeinite or potassium sulfate, depending on if I want to add Mg or not.

N deficiency. Dump the Lucas crap and feed with a balanced NPK with micros. Don't over think this.

Good luck,
