100% Cal/mag issue Raise the CalMag dose to 200 ppm at least and look how they react , you have to feed with cal/mag every watering . Good luck with your grow buddy 👍

I have added no addition nutrients other than what was in the mix initially. I used about 20 % worm castings to coco and the recommended amount of gia green 4-4-4, which is about 60 ml or 4 tablespoons.

Why did my pistols turn red so quickly? I did add some neem oil and recently began running CalMag but immediately stopped... Finally got ph tester and realized I’m running way to high. Got up/down coming. Any ideas??? Should I worry or do anything? Also, no males in there

Deficiency?Anyone seen leaf damage like this before? 6 weeks into veg in FFOF. A few fungus gnats but no real infestation. Not adding any nutes yet. Really concerned as the plant is looking less green and more yellowy than it did last week.
