Need help with my girl

My girl seems to be curling and leaf color doesn’t look right. I’m using just coco loco potting mix by fox farms with no added nutes.

its hard to say - but does look like temps might be getting a little high - what is the PH of the water you use?
To me, it looks like it may be getting a little too much nutes even though you say you aren't feeding, that soil likely is a bit hot. It doesn't look terrible, just correct your environmentals and if you want 'perfect' looking grows, I would just stop using 'pre-fertilized' soils as it makes things harder to control, I don't think this issue is going to greatly impact your grow here

Magnesium deficiency at the very least. Might be PH related like the previous reply mentioned. Could foliar spray with Epsom to correct quickly but will have to figure out long term reasoning… good luck

What is your source of water?

Coco loco is treated like soil. This last batch I have been using is a little hot but you don’t water it like coco coir.

Fair enough, I was under the impression it was coco pre charged with nutrients.

It is but it’s watered like soil. Straight coco is fed constantly. You don’t want to water to runoff with coco loco because you’ll wash all of the good stuff out. Just like ocean forest or roots organic.

Could be the light to strong
How far is it away and what power

How old is the plant?
It looks like the soil ph is off and could use a good flush. You will loose some of the nutrients but that can easily be fixed by adding some fresh amendments.

Its really that simple. If you want to go a different route, you can use liquid fertilizers. Liquid fertilizers require a little more finesse, but its not rocket science.
