This week the nice flowering continues. I bought a new light in China, Samsung LM301H 240W so I added it into my grow tent. The weak plant is probably destroyed and the yield will be very small.
@Simian5,
No idea, if the plant is older, I would suspect, overdosing on the nutrients but on such a young plant, I really don't know. The good message is, that it is not spreading and the new leaves are free of it.
