They are definitely stressed from underwatering, underfertilizing, not enough organics, to many pups removed, or removed to close to flowering, other root stress or damage, too many stalks in the mat, crowded roots, too much winter too close to flowering or a combination of things. You cannot change this bunch. You can only fix the problems so that the next bunch does better. Some sources claim that all of this is determined when the plant is still a pup. I can't prove that, but sometimes I see evidence that this might be true.

I have noticed a very slight increase in the size of the first six since they appeared.Would it be worth keeping just the first six and cutting off the rest of the flower so all the plants energy goes into these.
