little help

What could this be i do not believe its over watering cause im waiting till shes nice and dry prior to waterings i only use about 1 tablespn of nutes per gallon for now and ph is 5.8 ppm 550 im in coco and perlite shes about 3 and a half weeks old. Calmag defficiency maybe?

if you keep your ph at 5.8 you will lock out cal/mag, let it drift upto 6.5


the twisty leaves could be a temps issue if not PH

Thanks guys. I didnt think temp issue temp stays between 77-82 humidity from 65-80
