Well this has been a trying week in the grow tent! I started to see what I believe is nutrient lockout. Some lightening of the green on a few plants and also a bit of yellowing on one. I did my first flush with clear water. I also diagnosed a spider mite infestation, from gray spots on fan leaves. ( I think I introduced them by mistakingly putting some external garden plants in the tent early on) I treated with Pylon-Tr a total release aerosol. That knocked it out. On a positive note the buds and colas are starting to bulk up and getting sticky, and the tent is getting quit fragrant!
