Sativa or Indica dominant?

I have no strain information. I have a relatively tight growing space and need to know when to flip the switch on my plant. I hear sativas stretch further and I don't want to grow too large of a plant for my space. What is your best guess?

Leafs look more sativa but it is short and bushy so most likely a hybrid. I currently have a pla t that us shirt and bushy like an indica and di not stretch much but it has thin sativa leafs and stems. I also have 2 gdp that are full blown indica dom wide leafs and short bushy growth.

I would flip to flower if you have limited space.
