Leaves turning brown and crisp
LEAFJEstarted grow question 3 years ago
Dear Growmies,
My leaves, mostly the top fan leaves haves started to get brown and yellow spots. And even turn crispy to the point I can snap of the tips.
I already increased Calmag from 0,5ML/Liter tot 0,75ml.
I have been watering between Ph of 6,2 and 6,2.
Any ideas ?

Don’t up the mail msg, they only need ml to the gallon you give them. That looks like heat stress from your lights. I would raise your lights up a little bit higher a few inches or turn the percentage back a few percent if it’s a dimmable. I had that happen once with a Mars hydro a 80 percent and I fixed itself when I dimmed it back to 65. Good luck

I keep loosing leaves to some sort of nasty necrosis. It affects leaves at all levels, small and big randomly. I had to remove a lot of dying foliageAt first it looks like a asymmetrical spot of leaf starting to thin out to lighter color then tissue dries and turn black. I have high runoff EC3.3 and I blame Easy boost pellets because I only add rootjuice 1ml/L and sugar royal 0.5ml/L to my water. What is it and how I fix it?5 months ago
