For growing soil, choose Terra Vega during vegetative growth and Terra Flores when flowering begins. These are two base nutrients for different stages. The prefertilisation of your soil also affects when additional nutrients are needed and how much to use.
For coco coir, use Coco A&B. Both parts are used during growth and flowering, always in equal amounts and diluted separately in water. A is not a growth feed and B is not a separate flowering feed. Choosing the appropriate base keeps the programme clearer than selecting individual bottles by name alone.
