Sexing Before Flowering?

Is there anyway i could find out the sex of the plant before I put it into flowering?

nope,sorry buddy

u could do the paper bag method but i think its to much effort

after bout 4 weeks of veg they should sho preflowers and alot of ppl say not to flower till they sho preflowers it could cause hermis im not how sure that is but i do it any way
