my plant is about 17 day old and im wondering when i should switch to my 2700k lights for flowering. should i wait some more?
yes you should wait a lot longer depending on the size of your grow area, the veg. state is when a plant does most of its growing and thats where you get room for more buddage.
Yeah without providing details that is like saying "I need a new radiator...should I sell my car or fix it?" We need to know about your situation. Like is this a secret grow in your closet you are hiding from parents, gf, etc. How much space are you working with (pc grow, stealth rubbermaid, tent, whole room, etc.). How much weed do you expect to get (which honestly is a lot more complicated but does have to do with this). Everyone is different...different expectations and different situation. I live by myself in my own house so I can do different things than maybe people with roommates and parents. Tell us something more since most of us have converted our magical wizard hats into bongs or clone machines by now.
you can grow from seed under flower lights. wont get much bud tho. so the longer you veg the more yield. 4-6 weeks is good.
