I do use fertilizer on plants (all types) in two ocasions :
-When they ask me to
- Before the NEW MOON. That's the best time to roots absorb something, specially Biobizz that is organic and takes some time to be absorbed and integrated to the soil.
Less is more, no need to use the recommendations, only do that if there's a deficiency.
You should always remember that it takes time to the plant to show recovery signals from a deficiency, in this mean time you SHOULD NOT try to put more nutrients, that will lock the plant and will it keep showing signals of problem until it dies...
I do suggest you put small amount of nutes on them. these 3 products are incredible! They let the soil live, and top max take care of the roots and maximize the nutes that are already on the soil (if it has something on the soil).
