Hey everyone having problems with my plants this year, showing weird deficiencies or heat stress. This is an outdoor grow. All plants are in smart pots and I use reverse osmosis water. I've only fertilized the 3rd plant with fox farms vegetative (1/4 strength), the others have only received some calmag and fox farms root fert. Some of this looks like heat stress... it's been very hot with low humidity the past few days here. Any help is greatly appreciated 1st plant (Transplanted recently) 2nd plant (Transplanted recently) 3rd plant
Mist as much as possible when it's hot. I'm guessing you started them in side and transplanted them and just started with a full day of outside?
