Granddaddy Purple Bag Seed

9/29- Decided to shut the lights off this morning to see what they looked like without the purple lights. Started to notice some signs of some definite nutrient deficiency but not totally sure what Im missing, thinking maybe some magnesium and maybe iron but again not totally sure so Ill have to do some research. Going to be adding more pics with the light off from here on out to better gauge the health of the girls.** 10/01 was gone over the weekend, the girls are looking strong. #3 is 20.5in tall at this point and #1 is 16.5in tall. #2 turned out to be a male and is 22 in tall. he seems to have plateaued around that height and has been filling out quickly. I'm curious to see if my girls will respond the same way when getting to that height. Humidity has been between 63% and 70% and temp has been between 68F and 70F. light is 17in from #3 and 21.5in from #1 (will move up soon but trying to allow #1 to have some more intense light to keep it growing up to meet #3, will likely be smaller but I'd like to get the canopy's closer to the same height so I'm hoping that some light training my help)
