Killer kush/Northern lights 1st attempt

Another week in the bag. Northern lights fast- gave it a crazy hair cut again, to many big fan leaves hiding lower buds. I have been fighting a ph/nutrient problem causing the leaves to yellow/rust. I think i finally got it solved next week will tell. Only problem is that I'm coming close to an end so the leaves are going to yellow anyways. Killer kush- I didnt know it but the tips of some of the leaves are starting to purple a bit, didn't know this stain had this but im not complaining. The pistils are turning a nice brown and everything looks like it's tightening up. Overall another good week, the tricomes are starting to get milky here and there, and the grow then is super skunks. Both plants are starting to fill out a bit to which is nice. Shouldn't be much longer.
