Is this going to be a main cola?

My plants are showing sex and so far 4 out of 7 showing sex and they are all females!!!
Now i had some concerns regaurding topping/fimming.
I cut the tops about 2 weeks ago and i dont see two growth/colas. Did i do it wrong?

Out of all the plants i topped/fimmed only 2 plant is really showing signs of 2 top shoots and 4 shoots.
These were flowered when they were REALLY small plants. Only 2 weeks into veg cuz of some issues i have. So i flowered them for about 2 weeks now and this is the growth.
They are about 8 inches tall but im starting to LST them so the middle budsites get more lights.

Please explain what i couldhave done wrong or what i have to do for topping/fimming.

And overall how do they look!!!!
Strains are Northern Lights and MazarXAfgan. Total 30 days which 13 days are into flowering.!

Thanks

Should yield decently for the strain.
The tallest top of the plant will be a main cola.

In my experience,i have done what you have done, you will not achieve full growth potential and may be stuck with plants that are maybe 12 inches or so bigger. If you topped right around the same time you switched to flowering you gave the plant alot of stress around the same time. Topping works great when you let it recover (redistribute its growth hormones) so the lower nodes grow more. Keep the flowering going but definatly veg longer next time or use clones. Plants need to be ready to flower in my experience ie wait for preflowers.

How come only 1 plants showing two shoots and rest are showing 1 shoots but i topped everything the same way?

Did i do something wrong?

Thanks
