Pot committed: Plants too close in one large pot


Hello - I am new to the forum and this is my first grow in over 20 years. I am using a Tolys 1000w LED and an old school 315 HPS for lighting in a 4x4x7 grow box in my garage - 19hr on/5 off schedule since seedlings. Grow medium is black soil+much+tiny pebble river rock. Large planter has holes drilled into it all over and many holes at the bottom. Using FloraGrow x 1 week. Plants are on week 4 under lights and week 5 from bag seedlings (all kindbud medical grade hybrids that are sativa dominant). My questions:

  1. I have about 15 plants in the one large planter and I am beginning LST with a net. I have not spotted any males yet, about 4-5 suspect or possibly herme. I know this is dumb - but I am stuck with it now (I thought 1/2 would not make it, and half would be male leaving me with 3 or 4 ladies to care for…). What should I do now to maximize yield? Should I thin out the small plants? Let then all ride? I have plenty of air circulating and a 6inch carbon scrubber.Should I add more dirt and cover up the bottom of stocks with bud nods already forming? Any suggestions would be greatly appreciated.
  2. I have not flipped them yet, but the bud nodes are more developed than what I remember from the early 80’s (last time I had a victory garden). Do these look like they might be autoflowering?
  3. If they are not - do they look ready to slowly transition to 12/12?

Than likely they’re just pre flowers. Flip them any time.
Happy growing.

Appreciate the feedback. I am use to pre flowers not forming until after flipping.

Does anyone have experience with overcrowding and maximizing yield? I am on the fence with killing a few of the little ones to provide more room for bud development, or leaving them as is since I am LST with a net as soon as I flip them in about a week. And if no experience - any educated guesses?

Follow up: Here are the ladies 5 weeks under lights - 7 weeks from seedling. Girls seem to be thriving in one giant pot, grown in soil. Just into week 1 of fading towards 12/12. I wanted to link to another thread on this forum, but can’t find it…, that posted some articles on how plants share a beneficial fungus or bacteria and single pant per pot may maximize light to lower branches, but raising our girls in “isolation” per pot may be a mistake.

Here are the girls, two weeks into 12/12. Any recs from the pic? Should I start to cut off some of the big sugar leaves? Any opinion on trimming up the lower 1/4 of plant to stems?
Recap: Bag seeds, soil/river rock/mulch/coffee grounds/dried egg shells, bag seeds - mostly sativa dominant, under HPS 315watt and two LEDs 600W and 1000W. C02 DIY yeast/sugar. 4x4x6 grow box. There are about 10 plants in one large planter…

Notes:

  1. Hard to spot hermies that show up anytime through the grow process. Not a problem for ID males, but early spotting of herms is hard with all in one pot.
  2. Hard to early detect soil/fungas nats. Treated with dish soap, oil, and chilli powder - mixed with water and sprayed on nats in soil. Added fly/nat sticky trap to pot.

Grow journal note: Don’t make big adjustments too quickly solve a problem. Fast solutions often cause another problem. Treated soil fungus nats with oil/dish soap/chili powder spray on top nats and left fan blowing on dirt during 12 hr lights off. Fan leaves windburned. Interesting - all plants are sativa hybrid but one species was much more sensitive to wind burn.
