to dutch,do you think that the plants are growing to fast,the clones i mean?im doing studies on mine trying to find out what causes that.
to the op,are you letting your clones get root bound before transplanting?i use to have that problem when i first started cloning.i was so happy to see roots i want to plant before they died.try it again and start with a little more roots at first transplant,then let it get root bound before transplanting again.when i do this now the plants seem to explode when its starts to flower and you have done that last transplant.something you should look into.
