Hey guys this is my first grow and am currently 7 weeks into flower (from the time that the lights were switched to 12/12) but about 5 weeks from when buds started showing up. Right is blue dream while the left is blueberries. I’ve been adding half dosages of PK boost and not sure when to start flushing. The rest of my amendments are organic. I have also been seeing some slight rust spots on outer fan leaves and a little bit of yellowing as well as light green on part of the lower half of the canopy. Looking for advice since this is my first grow and happy to be pet of the community!
