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

Leaves burn
Hi! Is this nutes burn? Damage is on the upper/middle part of the canopy on very few leaves, but many more have black tips. I’m puzzled because during veg I was feeding the plant higher ppm than now and never had a problem!

Grey spots on leaves and yellowing
The leaves are looking light green to yelloe and there are these dark edges on the leaves are showing up.. Has anyone experienced this before? It was happening a bit before transplant but now it seems to be getting worse. I just transplanted within 24hrs... Stress? Overwatering?

RunWithIt
Popped up around last week (week 4, monday). Prior to week 4, i had been watering with tap water, which in my area is pretty hard.(7.8+ pH) Been correcting pH to 6.8 with each watering since. (2 waterings since then.) Should i just continue feeding 6.8 pH water or add cal-mag?

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.

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

Yellowing to slight grey leaves
What's the cause of the older yellowing leaves with some grey and the slow spread to the newer growth? I'm between pH problems and or deficiency but not too sure.
