Langbeinite is an organic amendment that has potassium, magnesium and sulfur. Its a naturally mined crystalline mineral that does not alter the ph.

Please help me diagnose this one :)
It is a very slight orange spotting that almost appears like the start of a calcium def, but without actually creating necrosis. It looks almost like the orange spots are on the surface of the leaf. Nothing on the bottom and it's only showing on the one fan leaf.

ButtersStotch
I believe I fixed my nute lockout a couple of weeks ago. But since flowering has started I’ve been getting a deficiency on the older leaves from the bottom moving to the top. I’m wondering if this is A nitrogen deficiency as I’ve backed off on the nitrogen since I’ve switched to flowering nutes. I’m not really sure how to proceed or if I’m even right.

Why DP's leaves are so small?
Hi guys! Do you have any idea why Durban Poison is growing so slowly? I am suspicious I might have hurt her during the transplantation. She has 3 pairs of leaves and she is healthy green, but her leaves are very small...strange from a sativa. She has the same age as my Durga Mata

Brown spots on top leaves - nutrients, light or something else?
She went into flower, now stretching. Set light to 100%, added Bio-Bizz Top-Max and Bio-Bloom (1ml/L each). 3 days later brown spots appeared on top fan leaves, very few also on lower fan leaves. I suspect this could be light burn or nutrient related. Any ideas? Pls help
