The bad leaves do not recover it simply stops other leaves from getting worse. Those are the nutrients I've used since '96. They are great and I use their drain to waste chart now but before that I used their recirculating chart. I started about 1/2 strength. If you have dried nutrients in your coco I'd start at 1/4.My bad this is the base nutrients i was talking about. And i dont have a ppm meter or a soil meter(bought one online never worked). And i tryed giving it cal mag but maybe it wasnt enuff but thanks for the help everyone hopfully it stays away now.
I'd also do an internet search for their original nutrient charts as I haven't really bothered to even look at their new ones. I also use their CaliMagic for my Ca/Mg additive but have used Botanicare's too. They are both fine. I prefer the Ca to Mg ratio in the CaliMagic produce.
