Mr. Grow It, thank you for all the information that you provide the community. I love all the YouTube videos, they really helped me get through my first grow smooth. I'm now on my 2nd grow and I wanted to run this by you. I'm growing some Amnesia Haze which has a 12-14 week flower time. My first grow ran about 8-9 weeks of flower and I was successful in cutting out the CalMag around week 3 of flower. I'm now in week 4 of flower with the Amnesia Haze and I'm getting some brown spots/rust spots on my lower leaves. Do you think this is an early sign of Calcium or Magnesium deficiency? Should i be feeding the CalMag later into flower now that I'm running a longer flowering period? If so, when would you suggest i cut out the CalMag?
