Hi, I am newbie here. I got auto candy cane and its 4th week from seed now, and I just fed her on May 24 with 2ml CalMag, 2.5ml Mirco, 2.5ml Gro, 1ml Bloom in 1 Gallon Overnight tap water and PH at 6.5. And the grow medium is soil. And the 900 watts LED light is about 20 inch away from the plant.
I am not sure if its heat stress or Nute burn, please help. Thanks
