  2. i use rainwater might it be cal mag deficency? i was planning on transplanting soon and add some dolomite lime to the soil...
  3. its like ph8 thats why i use rainwater ph7...the thing that happened was that i nuted the first two weeks (i know its my first grow) then saw the burn the flush a couple time untile week 5 then i only added 1/8 of the recommended dose..but want to flower it soon so i must transplant so if you tell that the spot on the picture look like cal mag deff ill add some dolomite lime or something else that might be better
