The plants still look a little hungary , but with the temperature outside dropping it has been down to 19.5 highs in the tent. So rather than adding my 500w heater , I have thrown in a Easygrow 100w led QB with Samsung H leds. I have given them a KNF foliar feed and bio enhancer yesterday, I'm hoping more heat and light will get them feeding well again.
Nice looking grow!! Running the same purple city Mac punch. Mine has stole the show at week 6. Pulled a couple of flowers and once dried looks white. Whitest white I've ever seen. Good job and good luck with harvest!
