The leaves contain the chlorophyll. Without chlorophyll the plant cannot absorb the necessary light for photosynthesis. Without photosynthesis taking place the plant cannot make use of these special plant foods no matter the quality of these products or how much is added.<snip>.... My question is if I'm adding bud booster and plant food to my water will that not make up for the removal of the leaves unless the plant goes into shock??
Often when a grower says that their plant went into shock for several days after the removal of these fan leaves they are right. The plant stops growing for several days until it produces the hormones for new leave growth to replace the chlorophyll that the grower removed.
The link below is a very short article or encyclopedia entry on "chlorophyll" from the National Geographic.
