They look like they're forming pre-flowering topical buds but a better closeup shot would help. I think I was taught an easier way to grow with an Aerogarden. Starting at twenty hours of light on and four hours off I gradually reduce the light at one hour a week every week. At approximately 14 hours of light and ten hours of darkness, even on the vegging formula I use, my plants start trying to flower, especially the males. Then there's no problem differentiating them.
The change in the light schedule is one issue but for flowering they're going to need a diet higher in phosphorus and potassium. I don't know what you're using for nutes, and everyone has their favorite, but I'd like to put in a plug for Technaflora's "Recipe for Success." It's a complete nutrient system and it's very user friendly. I was a dirt gardener for a long time and when I switched to hydro my local store recommended Technaflora. You can get a sample kit for about thirty bucks to get started and it has every thing you'll need. In a unit with a tiny reservoir like an Aerogarden it lasts for a long time and after a couple of successful crops you'll be hooked. You might want to at least consider it.
It's true that even with the 24 inch height of the super duper Aerogardens you're likely to have them out growing the unit. First of all, three plants have proven to be too much for mine. Their massive roots will become a mess. I limit them to two plants and they're even happier with only one. When they get too tall you can gently bend them over and let them grow horizontally across the unit. I tie them off with four pond test nylon trout fishing line and I weight and control them into the bend that I want with lead crimp on fishing weights. I think you'll find that works well for our height limitations.
Last, but not least, you have your spacer plugs up side down. They poke into the holes in the planting deck for a better seal. Good luck my friend.
