the young leaves look fine and are healthy looking. i havent gone crazy with chemicals i just use vitimins and fertilizer and i alternate weeks for the both. i just got my bahama berry and it is the first couple weeks for me with it so maybe im just over reacting about the spots. people i ask seem to think i may be watering to much however if it drys it dies. i have just been keeping the soil moist. dose anyone think i may be watering to much and that may cause a fungal growth? or maybe its not getting enough light? i put my grow light on when the sun is not the brightest it could be, how much "direct" sunlight a day sho8ld it be getting? also i just want to say this site is geat and thank you to everyone for your help. i dont know who i would ask otherwise
