The fish emulsion is a great supplement but does not replace a traditional npk fertilizer.

You may have an iron problem- notice the damage is most severe at the petiole?

You're going to want to use a complete fertilizer that includes micronutrients.
stinkyattic Reviewed by stinkyattic on . Damn, Big Problem So for the past few weeks i've noticed the plant getting lighter in color and I just came back from being gone for a week, and it's bad news. Ph is fine, i've been using tap water, i'm not sure the TDS. I've been fertilizing with fish emultion every two weeks or so so i don't think it's a nitrogen deficiency, but who knows, it looks like it's turning yellow from the viens outward. Any feedback is appreciated, Thanks. Rating: 5
