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

Lower leafs getting yellow tips and spotsI just noticed that the lower leafs are dying, while other leafs are getting yellowish spots. Is this some kind of nutrient deficiency? The leaf with the yellow spots is near the air intake.
They didn’t get any fertilizer except root juice since the soil is still somewhat fresh.8 months ago

Yellow tips at bud-leafsWhat is the worst case of what could happen to the buds and the harvest due to the yellow tip burn?
Since 5 days the near leaf buds have yellow tips.
It could have any reason. Flys, high ph, to high nutients.

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
