Hey folks, first time grower here. Something is seriously wrong with my plant and I’m not sure what it is.

Any ideas?

At first I thought it needed nutrients so I added fertilizer and it got a little better for a while. Then I added more fertilizer and it seemed like it got worse. I was worried I had over fertilized, so I watered the plants with RO water a lot. Then they got a lot worse and stayed wet for a while, and then dried out and seemed to start doing a little better. Today I trimmed off some yellow leaves to find that the new growth still looks messed up. I don’t know what to do!

    Those necrotic margins make me think it’s a K deficiency. I don’t grow weed, but I’ve got a soils background and nutrient deficiencies are a secondary skill.

    What kind of fertilizer did you add?

        Do you have a certificate of analysis? I tried to find one for this product but couldn’t. A COA shows exactly what’s in it and in how many mg/kg.

        Given that it’s fish/seaweed you could have a salinity/sodicity issue.
