Is this a Nitrogen deficiency?

What deficiency could this be? If anyone can help tell me how to fix it I would appreciate it!

It's not nitrogen, Look at the color. Nice and green. But the tips are hooking and burned. If anything it's a little high on nitrogen.
This plant is well into flower and finished stretching. Feed it a low nitrogen flower or bloom mix.

Take another look at the leaves. I see a mild Magnesium deficiency. You can add a little Epsom salts to your watering solution and fix this.
It would not hurt to offer some extra calcium as well.

I believe you are right… I should have cut the nitrogen back a week or so ago. This is my first grow and there’s a lot to learn. Haha

Thought its early deficiency nitrogen. Maybe u r right and its rather pottasium. I see tips of new, upper leaves curling down, that might be that nitrogen toxicity. Plant in early flowers demand more P and K, N<P<K. Ca<Mg<S

Magnesium deficiency. Mg is an essential element for photosynthesis. A deficiency often shows up in early flowering, so I recommend supplementing Mg at about the same time as the flip to make sure the plant has plenty when it needs it. I change my nutrient mix a week before I change the lights.

Typical 4th week leaf yellowing. It can be avoided. I keep pushing this chart where I use a regular veg regime of nutrients until week 3 of flower then I follow this chart and introduce Cal/ mag at week 3 and I've stretched it to 10 weeks because I don't finish until then
