First Grow 600w

Hello everyone, this is my first grow with LED. I have grown with ghetto CFL bulbs on light strips growing up as a kid. So you could say I'm new to doing it legitimately as an adult and legally. Like stated in the title I have a 4ft by 4ft by 6ft vivosun tent with a 600w vivosun LED. So to kick off this thread, I'm going to start with I got everything set up today. I will take pictures of the inside of the grow tent. I don't want to open it more than necessary. I will take pictures tomorrow, when the lights kick on in the morning before I go to work. I've purchased a critical Kush clone from the dispensary for $25 the label is dated critical Kush then tea under that Idk what the tea is for or what it means. But the date is 8/17/21 so this clone is about a month old. I wanna take some clones off it ASAP so i can grow more then just 1 plant for my first run. How many can i take now and not hurt the plant much and how many plants in the future can i grow efficiently and use all the space efficiently. In this set up But for this grow im fine with even 3 or 4 plants. Because I don't have another set up in general so I need to do my Grows All as one all the way through start to finish. Here where I live under the license and stuff that I can grow is 6 plants I'm not shoes sure if it's six plants in general or if it's six plants in veg and six plants in flower so I will look more into that but I'm curious what I be able to grow all six in this with the 600 watt light? In the future but of course be on that question let's get back to the whole point can I take two or three clones off of it now and it should be okay to the point they will be able to go into flower at the same time because I only have one set up when I take the Clones I will put them in a EZ cloner that has a dome which I will take pictures of as well but I'm planning on taking the clothes and putting them in the dome and I will just have them in the tent under the same light as the plant that I'm taking them from and then of course I will transplant them ASAP. By the looks of it as you can tell as well the plant I believe was topped once already. Here are some pictures of the plant. Thank you for looking and for your advice and comments in the future cheers!
