blueberry veging? how long?

i have this beautiful blueberry growing i started the 1st week of december, how long should i keep it in veg? what should my lighting be at? i have it at 24 hour light. thanks everyone for all your help. this is my very first grow.

Depends how big u want it to be but typically like around 6-8weeks depends though.. I did mine like 1 month after cause of the size.. Do you plan on topping?

what is topping?

topping is cutting off the tip to make it gror into a Y shape and you get 2 heads then
