Don't worry about it pal.
Some strains just take a little bit to get going, and can throw little tantrums and so on. Some might throw off mutations. Some might show signs of stress, (as you have done nothing wrong) as coly are up. And you are using a light mix.
Maybe, just give a small bit of grow or very very low ppm feed with whatever you have. Like 300ppm that's including tap ppm..
Good luck.
