Too many colas?

So this is my second grow. Veg under 270 watts of LED adding 600 watt HPS in flower, 4x4x6 Secret Jardin tent. Now, I have been working on a plant for a couple months now( training, cropping, topping) and have created a fairly bushy plant, 24" at her widest and 9" tall. She was found growing on a curb in a McDonalds parking lot (hence the name Kirby) so I have no idea what strain she is. My question, should I put a screen over her for flowering or should she be fine without it? Here she is.

Oh yeah, there are around 40 colas/budding sites.

I just remembered I have this picture from when she was found.

If thats the only plant going under a 600, i think you'll be fine. You've already trained it. I do think a screen would help hold branches up though. She will probably put on some weight sucking up that 600 by herself lol

AT MCDONALD'S!!?!?!?!?! THAT'S AWESOME!!!!

My apologies, I didn't share my full grow info, I also have a Cotton Candy Kush and two Jillybeans that will flower with her. Im trying to keep everything as short as possible, but now I have plants that are two feet wide and under a foot tall. I feel my tent is going to be crowded.

Any more input would be highly valued. Thank you in advance.

Clone some lower branches.. Flower one clone out to determine sex keep the rest going.. Maybe you have stumbled upon something.
Best of luck

I have two clones already cut. She is definitely a she. Definitive female preflowers.

I really appreciate the replies guys. I plan on flowering the 30th.
