Proper node spacing

Tried lowering lights. Did not respond well after a few inches lower and a few hours later. Put lights back and turned on bloom lights. Filling in better now. Read they will stretch quickly when hitting flower, so guess I'm good for now.

Some plants break in different directions as a result of stress, I think I see that in your plant's first node, which seems to have multiple branches with meristematic growth, a result of pruning, usually. If you have not pruned or trained your plant is probably stressed. Check my comment in week two of this plant's growth, there, you have an image of the a plant that has expanded in what seems to be an unusual growth pattern for that week in plant's life cycle. As I mentioned there, based on your application of nutes, you are applying 18ml of solution, where everyone else on the forum applies about an average of 7ml in flower and up to 8ml in vegetation. I'm not an expert, but the concentration of solution you are using might be a few times over what the seedling requires. This comes across again in the color of your seedlings in the same week, they are very yellow/brownish, which is not characteristic of pH being too high or low, or nitrogen deficiencies, which in week two are insane. Not to mention, that nitrogen deficiencies affect the leaves not the stem, and even your stem is extra discolored in week two. I can see the application of the CO2 in your stem's potential, it seems like that is being applied correctly. Lower those nutes levels and I bet you will see that plant thrive. you will probably have to repot.

I have not prunned the plant. Have done no stress training at all. Suffored bad light burn on all as a seedling, so I'm just trying to leave them alone and let them grow with correct lightling and nutes. It started out very bushy with little to no room between the nodes. I put a CO2 bag in and it has since stretched quit a bit, but is thick stemmed. I read they stretch out during flowing, which they just entered pre-flowing based on the white pistols just forming end of last week. I know I read that strain plays a big role in it too. It's growing around just over an inch a day now. Spacing doesn't seem to be increasing much over the last day or 2. It's a 100% indica strain called The Hog from pacific seeds bank. Supposed to yield about 600g a plant if in perfect environment, which it's far from. I'm using 2 strong 4000w lights at 49 in from canopy reading around 6500 lux which according to waveforms conversion is about 570ppd. The manufactures light chart shows 30 in is 1,161 ppd with about a 6-700 ppd drop for every 6 inches. According to that, they would be around 570ppd at 36 in. So about a 13 in difference in the 2. Not sure whether to leave it since they seem to be thriving well under it or drop if some for higher yield chance.

Hi, I wouldn't say it's too late, but based your plant's morphology, I can tell you pruned her without a plan. As the previous comment suggested, you can try lowering the distance of light relative to the plant. However, that is unlikely going to result in her slowing down that uncontrollable vertical growth, remember that pruning inspires new growth, both horizontally and vertically. If you prune with width in mind, the plant tents to expand horizontally, but if you prune without a plan and just take leaves out here and there, that plan does not account for vertical growth, so she stretches in a way you might not have been intending, because vertical growth was not considered in your approach. This is my conclusion, it seems like you pruned from the top down, whereas most growers prune from the bottom up, so as to promote horizontal growth. I can tell you pruned from the top down, because there is less growth at the top of you plant, where new growth is supposed to be, than at the bottom, where older growth sits. Next time, try pruning from the bottom up and with a plan on what fan leaves to take off from there, because even what leaf you take off matters. Last advice, try taking off two leaves at a time in your next go around, see how that effects the plant's growth. Then, consider studying this stuff at some college, if you are going to take the time to come up with a plan to do science, make it a career. The industry seems to be appealing to scientists, if you are fine with your plant as it is then you are a hobbyists. Clearly your not.
