I have been noticing discoloration at the tips of the two largest leaves on the plant. The leaves are yellow-tinted, and dark spots are appearing on them. I'm worried this may be some sort of disease, as one other leaf also has discoloration and a small spot on it. Any ideas what this is and how I can prevent it from killing my plant? The plant is still quite young.
A picture would always help a lot. Please answer these questions, it will help us diagonse the problem. What type of medium; soil or hydro? What brand and type of soil? Indoors or outdoors? What strain? How old are the plants? What type of lights and how many watts? How far from the lights? What is your watering frequency and source of water? What, how much and when was it fed? NPK? What is the medium/runoff pH and PPM if in hydro? What are the temps and humidity in the room? What size pots? Any bugs? Look real close. Any other pertinent info?
