Nice flowering but one plant is struggling. I have reduced the nutrients. Flushed by water. The weak plant is still growing but the yield will be low. It seems that Purplematic CBD Auto needs a bit less nutrition than Northern Light Auto.
@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.
