Do I need to top soil and can I?

IMG_20210425_130128288.jpg So I'm back with another question. I was feeding this morning and noticed visible roots at the top of my medium. So I'm wondering should I top soil or what should I do? 4 weeks into flowering now and like I said in my last thread I'm in back yard soil. On the other hand she's doing good.

They look nice, buuutt, what's that net doing for you? are you just using it for support? Open her up? Trying to reduce weight strain on the stems? I ask because there is sooo much wasted room. Is she an auto?
 
No first time, thought I try a scrog but didn't veg. long enough got to anxious . Next time I'll let it fill up. Have 3 bubblegum fem in veg. now but did a manifold this time around.
 
Also it's a og Kush, bagseed. First one so learning as I go. Bubblegum fems. from seedbank. Post pics later. Maybe get some feedback.
