Hey y’all… currently growing 2 plants of the same strain and breeder. Blue gelato 41 from Barney farm. One is healthy and thriving. The other one is a little behind from nutrient issues. At first i had rusty brown spots, my buddy at the grow store gave me some cal-mag and it seemed to help. I treated it again a with cal mag the following week. Now I’m worried I have burned it. Any advice would be great, thanks and much love.
