Indoor 4 x 5 tent here with a single 1000w metal halide bulb in veg/HPS in flower.
This fall, I've got four plants in 3 gallon pots in there -- two Laughing Buddha (on the left), and two Amnesia Lemon (on the right). Both have been in veg for about 8 weeks. Both are seeds from Barney's Farm.
I've topped each one two times -- the first time, just after the 5th node, and the second time, just after the 2nd node on top two branches.
About a week ago, I slipped this net over the top. Today, it's tie-down day. It probably sit around 4 inches over the top of my soil.
I'll continue to grow out this screen for another week or so (still determining that) before switching to flower. A few days ago, I thought I would wait til around 10/10. However, I'm starting now to think I have to do it sooner. I should know after today's tie-down project.
My feeding regimen is pretty simple: I am standardized on Gaia Green, and about a week ago, I began transitioning from the 4-4-4 veg mix to the 2-8-4 bloom mix. I supplement with EWC and urine diluted 1:10. I'll stop adding urine after about the second week of flower, and top dress with GG 2-8-4 and EWC mid-way through flower. I pH all water to 6.2ish.
My light footprint confuses me a bit. The single-ended HPS bulb tends to put out a slightly rectangular light pattern. I've measured it at about 20 inches long and 18 inches wide (which seems STUPID small to me). To get the proper PPFD on the canopy (about 800-900), I find I have to keep the 1000w bulb about 18 inches above the canopy, which is closer than I expected and makes for that small 20x18 light footprint. This bleached/burned my last crop a little bit, and I think it hurt potency, too. I'm trying to keep these two plants a bit further away this time, even if it means my PPFD and DLI drop closer to 700 and 40.
I'll share some pics after the tie-down, along with a firm flip date.

Urea is available to the plant immediately, so it's useful for quick turnarounds. Even better, it only stays in the soil for a short period of time -- it's pretty easy to flush out (no pun intended). That's helpful, since you don't want too much nitrogen hanging around into late flower. So I consider it like a N hit team: in and out, fast, no marks (all organic). Edit: and no, to answer you directly, it's not the only nitrogen I use. I actually mainly will supplement with blood meal and fish emulsion. This time, I am trying to see how Gaia Green does without a lot of supplementation, because I'd rather simplify my grow process while remaining organic, and GG seems like a good way to simplify. I decided to supplement with diluted urine only because this time -- since my goal is to grow flat -- I'd topped a few times and wanted to give a boost to further veg before the flip.
