New grower, black spots on leafs curling.

Discussion in 'Sick Plants and Problems' started by Mark Donaldson, Jun 29, 2019.

  1. I noticed that a few of my plants have developed these black spots and the leafs eventually start to curl where the spots are. Any suggestions?

    I tried to stay away from over watering as per much advice from veterans. I have been pretty conservative on the nutrients.

    RH is roughly 50%, hygrometer is a bit off. Temperature is right around 25C or 77.

    Light is an optic 6 hung at roughly 50 inches to be safe as it is quite powerful.

    Any advice would be appreciated

  2. Looks like lockout, most issues are ph related so you need to find out your in pot ph, have you done a run off test? Not 100% accurate but will give you a rough idea of where you ph is at.
