Thankyou all again for the feedback.
not sure exactly what it is, but some pest is chewing my plants bare. it's no insect, and every time I visit the plot I see at least 3 rabbits hopping in and around the area. I've concluded that it must be them, as no mouse or rat would be able to reach that high up on the plant.
it's becoming a serious problem, I'm afraid the stressing from losing the fan leaves might be forcing the plants into males or hermies. I'm not overly pleased with the DoubleGum, it's either a late flowerer or has a very poor m/f ratio. none of them have shown signs of flower, except for 1 which I am about 90% sure is a male, that will likely get chopped on my next visit.
tonight I'll go out to the plot again and I'll be putting up a small fence around it to keep the vermin out. I might snap some more pictures if I bring my camera.
stay safe :rasta:
