Seeing some top bud leaf discoloration
aRecreationaliststarted grow question 5 years ago
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

Yes it could be genetics but it looks like molybdenum deficiency.
It is often caused by low temps and excess sulphur. It should be nothing to worry about tho!

Gray leaves on buds with a massive concentration of trichomes. What is it?No clue what this is. Light gray leaves, tons of trichomes. I'm a bit confused here. Should I just cut the buds that look like this to be safe? Or is this normal?
