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?

Black spots spreading // Need your help!
Anyone got a clue what this dark spots could be? It started in a corner of the tent with 1 plant a few weeks ago and now it has spread to another. I suspect pH issues and a nutrient lockout bc of that. Not sure if its the same issue though..Could be an infection as well...

Black spots under leaves
What are these black spots? I recently released some ladybugs in my grow room and saw them crawling on the plant this week, so is this possibly from them or from something else?
