Nute burn or nute deficiency?
I am growing a single Dark Start in a space bucket and running the Fox Farm basic nutrient plan. I am in week 6 of the 10 week flower period, and I’ve noticed a couple things that I am concerned about, and I was hoping to have some more experienced eyes on it. Full disclosure- I’ve also been flushing for 2 days with pH balanced water too, as my first thought was just nute burn.
So my thought is that, given the deep green color and some of the curling of some mid plant leaves that I have/had a nitrogen abundance/ borderline nitrogen toxicity … I have some burnt tips (which I think came earlier on when I overfed a touch), but I’ve also started to notice some small brown spots appearing area the main vein of the leaves. Could I have an abundance of nitrogen but also a manganese and/or potassium deficiency at the same time despite no yellowing?
And one more question- once I fix the issue, I know the burned tips won’t heal, but will the brown spots in the mid leave heal or no? Just curious how to gage the progress.
I’d love your thoughts and advice. Thanks all!
