Anyone give me some friendly reinsurance.... and topping advice

I am about 30 days into vegging now and my three OG Kush are between 8" and 10 1/2" tall. I was hoping to have them end up being around 3-4ft tall. I was going to try and top the smallest one just to see the difference but arent really too sure on what to do and I dont know if it is too late to top... i have some pics to help also I am a little confused about cloning.... The way the branches look they dont look the same as other clones Ive seen. Mine only have like one main branch and a branch growing out of the node.....

anyways any help would be helpful..... ohhh and I was also looking for jsut to see if they looked good or bad or anything like that too

Nah, it's not to late to top. I would actually wait to top like a few more weeks if you want them 3-4ft. What nutes you using?

Go ahead and top them if you don't plan on going 12/12 for another week or so. Also I'm finishing up an OG Grow and my girl ended up being 3.5ft tall. WAY to tall for my dr80 I made her fit but just by the skin of my teeth. I say you should top them and veg for another 2-3 weeks.

You will probably want to flower very soon if you want to keep it to 4 ft. It's about 85% Sativa so it can get tall.
What soil, lights, fan, and nutes are you using?
There are different topping techniques. But a simple one is to wait one week into flower 12/12 and cut the top just above the last node and you will get two colas. I've topped different plants at different times but it depends on the plant and the growth characteristics. You should be able to do an internet search and see how it responds to topping.
Someone on here has probably grown it.

Well ive only given them nutes once about 6 days ago. I am using jacks classic duo..... very very nice nutes and cheap. i have 600 watt digital ballast with a MH bulb in right now and a HPS for flowering. they are in 1 gallon pots with FFOF and I have a carbon filter and 6" exhaust fan at 424cfms.....

So what do you mean the top node like just cut it off?? LOL ill look around more but ones I have found want me to cut my plant in half and i am just scared hahah its my first grow and I have worked hard on grwoing them hahahaa

Don't top... try LST instead.. basically keep tying down the tallest shoot.. Works great for me. Really bushy plants with tons of bud sites.

Exactly what is meant by LST? I mean I know what it is but am unsure where to tie the node.
