this ^^ and also any nutes your feeding the plant are most likely trying to push up the plant into the flowers, I dont know a great deal about cloning but I do know about how the metabolism of the plant changes after turning to flower, and 85-90% of the growing power is not going to the roots at that stage, its goin up top, root development pretty much stops, that mean the roots must be well established before moving on to your next stages, other wise the plant will suffer greatly at the end of flowering stage, more roots means more mass up top.
Try not to dote over them too much, you would be surprised how tough they are, it's not called weed for no reason
all that being said, they looking much better now, good luck with em
