Ok. New issue. Plants were still kinda light colored, and were growing, but not as quickly as they should. Tested soil 3 times at different locations/depths and always came back N deficient. Gave them 1/4 serving of Grow Big. Yesterday they seemed to grow a little more, and perked up some. Now, this afternoon I noticed these red/orange spots and taco leaves. I looked around the forum, and it looks like I need some cal/mag? Do the experts agree? Or is it nutrient burn. It’s definitely Orange, and leaves are not drooping, they are curling up like tacos.
