Ahhhhhh bro u should of got the advanced nutrients sensi calmag since u already had the brand. It almost looks like calmag deficiency. Mine looked worse than yours and I started using sensi calmag and rhino skin and in 3 days they were nice and healthy looking. Check out your instructions for your mars hydro and it probably says somewhere to use Xtra calmag. There's something with quantum board LEDs and calmag deficiency
I read your last grow and saw you had it stolen. If its your friends and I say the word friends loosely as friends should keep stuff like this to themselves let it slip about your grow, and if they know you run diaries they could just wait until you report your harvest and then rob you of your finished product. Just a thought.
Looking good and progressing very nicely !! Good luck !
