I went from MH 18/6 to HPS 12/12. How long before I see flower signs? It's been 5 days as of today.You switched to 12/12 right? Some people keep the MH in for the stretch then change. Anyways depending when you flipped to 12/12 it could b upto a couple of weeks They dont look like pistils to me, just parts that are on every MJ plant GL
