Dunkle Flecken auf den Blättern.
Hey.. On one of my White Widow plants, dark spots have been appearing on the leaves for days, and today I've also noticed the first spots on a Blue Dream.. Can someone tell me what's going on and how I can get rid of it? Removing the affected leaves hasn't helped.

Grey leaf tips
Booth plants are showing some kinds of burn and I am not sure if it is nutrient burn or light burn or if there is something missing. Looks a bit like MG deficite but shouldn't the plant take that from the soil in that state and age?

Hey friends, can you tell me what this could be? Should I be worried? It seems to be doing fine and it's the only leaf with spots, could it be due to some water accidentally falling on it? Thanks

Please see the 2 photos marked in the diary. Is this a classic PK burn? Did a feed with no MegaCrop, no cal-mag, just PK boost at diluted dosage. The coppering and yellowing has come sudden. Leaves are crispy where burnt. I hear its easy to burn with PK boost. Did I do that?

Seeing some top bud leaf discoloration
Starting to see small dark/black discolorations on the leaves. Since I don't know the genetics, I can't tell if it's prone to dark leaves. Could it be signs of anything else? Note: Started watering only using TopMax and ActiVera because of some possible Nitrogen toxicity
