A question from a fellow grower:

type on my plant in the vegetative stage so long the Nitrogen And
phosphorus are in higher ratio and in flowering stage Phosphorus and
potassium should be higher … Please guide me through thanks

Always start with a balanced fertilizer. 10-10-10, 150150150…whatever.

Maybe even a 5-5-5. A lot depends on your grow space, and pot size; Among other things.
