What nutrient boosts flowering and strength - I’ve tried searching forums but not found the answer

[AthelR]

As the title suggests, I’m trying to understand how to feed my plants in the late flowering stage. We have lots of small colas and need to boost them before they go to harvest stage.
thanks for any advice you have. X

Do you have a picture to explain what you mean by small colas? Are these lower buds?

How late in flower are you talking about? When do you plan to harvest? Late flower usually means too late for feeding.
