I'd really like to know asap what sex the plants are. It's the second to third week into veg. and they are about 3-4 inches tall, 4 nodes. They've been 24/0 for from seedling to 2 weeks, and now they have been 16/8 for the past 4 days. How soon can preflowers show? Do male preflowers appear faster than female or vice versa? A couple of them are looking like this. The other two have nothing on them at all.
