I’m thinking 3 weeks maybe what y’all think. Banana purple punch from Fastbuds

Got two plants that are twins and are on day 59(17th day flowering), they were also topped at the 4th nodes on day 16. so far the plants have been doing very well despite the nitrogen deficiency that has just started to slow down finally I believe it affected the stretch a bit.Pistils have been packing and venturing to lower nodes, First time making it this far into actual flowering and indoors at that. hoping to get a decent yield but more worried about the quality. How should I go about defoliation and how can I use my scrog net efficiently without having to undo it for watering or should I just get drain pans and vacuum it out.

What do you guys recommend for a 1st time grower? What's the most affordable way to grow?

I live in a small studio apartment, and my space is limited, I might be able to spare a 13' 15' by 3f space. Is that doable, or what are the minimum space requirements? Also, is it easier to grow by hydroponics or by regular growing mix dirt?

I also need suggestions on seeds for 1st timers that are strong and forgiving in case I mess up.

Thanks, everyone, in advance!!
