Tip of leaves curling down


#1

Can someone please tell me why the tips of my leaves are clawing down like this? The strain is Auto Northern lights.This is my very first attempt at growing anything. I started with one plant to put all my attention on it and learn from any mistakes. I am in my first week of flowering, using the roots organic original soil, and the roots organic nutrients. I have only gave them one feeding so far of nutrients, so I found it hard to believe it could be nutrient burn. The leaves do not have any yellowing, the only ones with some yellow at the tips are the newer developing leaves at the top. This leads to my next question, I also read that leaves can get the clawing look from too much light? I moved my light up a few inches, but so far the leaves are still curling downward. I am wondering if I should try to flush out my system to see if that helps, or if anyone has any other advice it would be much appreciated. I respectfully request any help that anyone can give me. Here are some pictures.

This is all well and fine but with out a pic under regular light it’s but imposable to give an affirmative account of this deficiency.

Reminds me of a Seinfeld episode where George walks into a meeting, sits down. Tells a joke. Everyone is roaring laughing and he gets up and walks out of the meeting to leave on a “high note”.

Thanks and I’m outta here!

I’m sticking with my answer… I’d wait and see what @garrigan62 had to say though. He’s a pro, I am not.

Nice plants though! :+1:
