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

Small markings like that randomly appear on plants often. Specs of dirt maybe? None of them appear to be a deficiency except pic 3; one could argue it's the start of phosphorus deficiency. Although, I wouldn't consider it that until more markings like that show up on the plant. I don't think you have anything to be concerned about at the moment. Anyone else have thoughts on this one?
