That is what I have done so far, moving leaves behind other and using the fan leaves to push the stems outwards towards the light. I have been removing the yellow weak leaves but a few large fan leaves low down had gone yellow and dried up so I hope this is ok?
A friend told me that the bud development on the stems needed light and to remove any leaves getting in the way hence why I raised the question, but leaving them on even if they are blocking the bud is better as the light received in those leaves will go into the bud production anyway?
