Claw, light or something else? Have not been using nutes

As the subject states I am not using nutes and watering about 1/2-3/4 of a solo cup of stale, pH balanced water every couple days. My light is 400w mh is vertical hanging, hovering with the end-cap just about plant-top 6-7" away. So no real heat can even be felt by the plants. Any thoughts on the curl?

It's not the lights/RH or heat at the area between top cola and lights...
I have found that...
If it was, the leaf tips would point slightly up...
Your's are pointing slightly down...
Maybe a slight over water...
As plants dry, keep notice...
--Plants look great... I would not worry...
Soon you will be adding nutes/ferts ...
First time do not use with ultra dry pot...
roots 'could' suck up too much first time and brown tips will follow, pointing down...
Add first "Feeding" with a slightly damp plant, as to not shock roots...
If you use 20 OZ of water per plant... each time... use 10 OZ water, first...
Then add 10 OZ of food, on top of damp medium....
With looks of plants so far, you'll be fine....

Thank you. I appreciate the simple, detailed answer. As a side question, and I'm not sure if it's always assumed, but is using nutes/ferts a must-do? Or does it simply add to the end result in quality?

This is my thought process as well. I don't believe it is toxicity because you have good leaf color. You will see darkening leaves long before leaf curl is in the picture with toxicity. I think it might be just a slight bit of over watering. I had the same thing happen with 2 of my Goji OG's, and they had never been fed nutes. If you have transplanted recently it could also be due to minor transplant shock.

The link told me a few things I didn't know so I saved it. So I think in your case you may be having beginning signs of N tox even though you didn't add any, your soil mix may be a little hot to start with as some strains ar more susceptible than others. Im leaning towards N tox because your leaves are a little dark. If your medium is sterile and since you haven't fed it anything yet the only other thing it could be is a moisture issue. In any event it's curable at this point. Moisture issues are easy to resolve. And if it s beginning N tox you can leach the soil with water and some of the N will drain out the bottom. No fertilizer with N for now. Perhaps a week P and K in a week or so. I'm not sure if you mentioned what soil mix you used. Can you tell us a little more about that?

Two strains: Royal Queen - Power Flower & Heavyweight - Fruit Punch

No recent transplants. It's a few weeks.

The soil is a mix: 3 qt Perlite, one coco coir brick and the rest Miracle-Gro Moisture Control Potting Mix.

If you look on your bag of soil you'll notice it has NPK percentages on the back of the label. that label itself says it feed up to 6months (if i did look at the right one the other one says 3months) majority of miracle grow has feed in it so when you water you're actually feeding it.

So I looked up the product on Scott's website. The analysis is .21 .11 .16. But those time release pellets are not fool proof. I know a woodies grower (trees and shrubs) who told me (they don't teach stuff like this in school) that Osmocote (a brand of time release pellet) dumps all it's load in high soil temps. So even if the pellets in the Scott's product dump a little more than normal it could explain the symptoms in your situation. As for the remedy it's too late to repot so I would figure on leaching the soil with water to remove any excess N and as a precaution I wouldn't feed your plant anything for the remainder of the grow. The Package says it feeds for up to six months, more than enough time to grow it to harvest. About the only thing I would add is a little lime. 1tbsp is more than enough and scratch it into the surface of the soil. I hope that resolves your dilemma and remember for the next run not to buy a soil mix with time release fertilizer. You want that control yourself.

I gave them a good dousing of water yesterday. I'll wait another day or so before doing it again. Thanks to everyone for the input.
