Inaugural Grow: Auto Northern Lights

I think you may have started a little early. I wait until there are about 3+ nodes usually when she sprouts her first true leaves. I’d take a little pressure off and start maybe a week or so later. You really want her roots to anchor down a bit more! I’d also support the base of the stem before you start pulling the top down as well! I hope this helps!

I agree with the previous comment. You really don’t want to let one go and lst the others, you will have problems with it later on in flowering. The one you let go could go 2-3 times higher then your lst canopy will be. The other option if you really wanna keep your Control plant is to buy another led light and move your lst plants to one sine of the tent together under one light and use the second light over your control plant.

Hi there! She's starting flower but you can keep using veg nutes and gradually lower the nitrogen in the next 2-3 weeks. The first weeks of flower is the stretch phase and they need lots of nitrogen in that time so it's good to slowly change to full flowering nutes

You had the TDS at 2250ppm to me it's too high, sometimes those spots are related to drops of water that acts as a magnifier, Are you having those spots on a few lower leaves?. Cheers

Tds too much high, less nuts and more water. See your PH. Happy growth!

It is pretty normal for the leaves at late flowering to go yellow, so nothing really to worry about. The close up picture looks like that plant is close to harvest, don't worry about "amber trichome percentages" some plants will never have amber trichomes and some plants will have amber trichomes very early on, depending entirely on genetics. I am a bit worried about the first and third pictures, there seems, what looks like to me, a fungal problem starting to raise its ugly head, with the black blotches being the tell tale sign. I would be stopping all nutrients, letting things dry out a bit and only giving water for the next week or so and be considering harvest soon rather than later. You don't want all your hard work and big chunky blooms going mouldy. Perhaps if you haven't fed them for a few days, harvest could be brought forward a few days. Remember, you will never stop learning when growing this wonderful plant and as a self described "newbie", should be proud of your results. Think how much you learned this time and how you can apply that knowledge into your next grow. I have been at it for 35+ years and am still learning new things every season. Congratulations on your adventure into the wonderful world of gardening for pleasure! Hope this helps... Organoman.

Trichomes look similar, eh? Resources are spread out as opposed to a more focused used on the untrained plant. You get similar yields. I'd wager the strongest correlation as far as plant structure is the root system. Obviously giving max DLI relative to ambient environment being the single biggest factor for larger yields. #1 has more colas than #2, right? So, it's colas are a bit smaller. Sometimes training can stall a plant. If you didn't notice a slowdown, i'd wait for the dry weight before assuming anythign about yield. it can be deceiving still on the plant.
