unsur if this is were to reply... Im going to persist. probably lower feed and I think im over watering so will allow more dry out time. maybe just use pure water in the next couple of waters. I did notice the over green colour of the leaves and i did take out the nitrogen feed but I looked at the canna feed which does still have trace nitrogen.
So im going pure water and longer dry periods.
hopefully this will have a positive affect of the buds.
