Hermie is undesired in medical marijuana if you are just a stoner wanting some free bud or a kid who cant buy then a hermie wont bother you.
If I grow bud and it hermies I am pissed pretty bad over that because it turns a 50,000 grow to a 20,000 grow.
Seeds diminish herbs value and its potentcy.
Without seeing your grow and just reading what you write I would assume you are not running correct lighting and havent put really much into a grow room or a setup. I could also assume you havent planned ahead.
If your plant is skinny/skraggly and leaves small that is a sign of stretching which is stress. You are already growing a strain that isnt very stable(likely to go hermie) and are stressing it even further.
I would suggest buying some lights 250-400watt switchable ballast(means it can run a MH and a HPS bulb)MH for veg HPS for flowering.
Invest in some mylar its around 50 bucks for a 100ft roll 2 mil thick.
Growing costs a bit of money to start if you go cheap you will grow cheap.
If you dont have any money to invest in some lights you can always replant them outside.
