Generally no - male clusters are huge. There can be as many as 30-50 preflowers near a node. With female preflowers, there is a single preflower, sometimes two (on each side of the node). In addition, the females will show usually a single or dual pistil extending from the node, whereas the males do not. Even in *very* early preflowering, females usually exhibit at least a single pistil. If you have more than 3-4 preflowers in a single confined space at a node, it is probably male or hermie. Let it flower a little more to be sure, but chances are it is male. If there are less than 3-4 preflowers, then you will absolutely want to flower it longer because sometimes pistils will hide a little longer than usual and it would not be cool to hack a late blooming lady.

Pictures? Many of us can probably tell you what you have if we can see the preflowers...
