PLEASE HELP TWISTING LEAVES

I have these three girls that are about 6 weeks old in veg i transplanted pots from a1 gallon to 5 gallon and moved them into my flower tent about a week ago. One plant is completely fine but another one had real bad twisted leaves on new growth and the other has brown spots on it. Im thinking that the britten spots are some type of deficiency or toxicity. Im not sure of what though. Any advice would be greatly appreciated. Also im using coco perlite mix that was used once before but rinsed before using.

Looks n tox. Maybe some lockout, nothing major. What strain is it? Some strains do this always in varying amounts.

Weddings cake would you suggest a run of stright water
