Curly At Edges Of Leaves

[Paulcnumber3]

hey guys. I have clones and it's my first time ever making clones they are doing great but I noticed in my veg room 18/6 that my leaves are curling upward. I only have 1 led light that's small and at least two feet away from the plants. I did use a new soil. I used some organic compost, coco fiber, and black gold and amended it with flower girl from dr earth, dr earth bat guanno and some kelp meal. Is this nutrient burn or possibly due to high humidity. My reader says 80% let me know boys all my flowering plants are not having he same problem under similar light setup and in the same grow room.

Pictures in normal lighting are always better. Are you certain that you don't have spider mites?

Possible heat stress
Possible russet mites

Heat stress. What are your temps?

If they are "clawed" it's over watering.

I believe it was a huge fluctuation in temps 80 in the light under 60 during the night. Moved everything in my basement. I believe that and new growth was what did it. Thanks for all the help guys
