How long until I should top the middle? I got 7 nodes so far and there’s 42inches between light and top net pot. 33 days since seed.
Sativa leaning green crack but seems like a bush to me :)
That's really up to you. It doesn't appear to need topping to me. Also, I've never used Quantums but it seems you have an aweful lot of distance between the fixture and your plant. Have you talked to anyone knowledgeable on QBs to find out your fixture's PAR(PDI). Your plant looks a little underdeveloped for it's age to me. I'm figurin with QBs you should have far more growth than that by now. Not knocking your plant, just trying to help you out.
What's your plan for the 12/12 flip? Do you have a light-proof enclosure or tent for blackout during the dark 12hrs? How big do you intend for it to get before you flip?
I'm not asking these questions because I want answers. I'm asking so you can formulate a plan. I'd also flip that net horizontal if she were mine. Use it as a ScrOG. If you're running a net verticle it needs to surround the plant like a tomato cage. If horizontal then it needs to be set up like a ScrOG to control the tops or set in multiple layers layers for support. I'm not quite sure what you're doing there, or maybe the pic has an odd perspective and is just confusing me.
So you know, I'm not being critical to pick on you. I'm trying it to help you if I can. It looks to me like you've picked up a lot of information about growing but haven't quite got the pieces put together right. I tell you though, it appears you are way far ahead of where I was at that point.
Go ahead and tell me what your plan is and I'll try to walk you through it and get everything in the right place. On thing however, it looks like your running some sort of hydro system and that is an aspect of growing I have yet to learn.
