I’m new here so take what I say with a grain of salt.
First, fem seeds should not be male. I’m going to assume you are at 7/7 which would be normal for fem seeds. Let’s take another close look at the questionable one in a day and a half as you say, but I would be hesitant to remove it unless you are really positive. I’ve had bad experiences with getting the wrong seeds before, but Herbies is generally pretty solid. Were they original breeder packs?
Since you have already flipped to flower, you do not want to be too heavy handed with high stress training like topping the plants. But I think you are going to have some height concerns soon.
According to Herbies, lineage is Chem Sis x Sour Diesel x Chocolate Thai
50/50 indica sativa
You are getting some tall plants there, and should expect a significant stretch. Some of the height is due to the lack of blue / white in your light, and also how bright it is (isn’t). We can’t change that right now, but as you get further into this, the difference between the shortest plant and the longest will become worse if you do nothing. The shorter plants will not receive as much light.
I think I would put some buckets under the shorter plants to try to make your canopy even today. Give the shorties the best chance. And I don’t know if you were planning to add a net or trellis, but starting to bend that tall one over and holding it down (low stress training) can also help. Your goal is to have an even canopy when you get to full on flower.
200CM tent height = 78 inches. that means you will have about 60 inches to work with if the light is all the way to the top of the tent (careful of heat / fire). You have about a foot in pot at the bottom, meaning your plants have about 4 feet or 120cm total to finish in. You are getting close to that already on the tall one, still have the stretch to go, and then you will be adding buds on top of that.
You got this, just do a little planning, a little reading on lst, and get in there and make those girls happy.
