First Grow :) Lamb's Breath

the plant will only canabalise itself during the flower stretch if it doesn t find its nutes in the soil or through it's foliage. The rate at which the plant will seek out nutrients depends on its metabolism which in turn depends on the light schedule and the "vapor pressure deficit" (VPD). You're 10/10 VPD-wise, and your light schedule is intense actually so you can expect BIG growth ! Big growth means more nutes needed, simple as that. Therefore you should for sure expect to see some yellowing, starting with the bottom fan leaves. Since you're not going to be giving any more nutrients, you need to keep an eye on what's going on - there will be "expected yellowing", but you need to stay on top of it in case you run into som "unexpected deficiencies or related problems... does this answer your question at all? hope this helps ! 🚀

Congrats on the cool new kit ! Yeah trichomes are the only thing that matters, after all pistills will turn Amber once you chop , and how quickly or even if they turn Amber is strain dependent . So you want to check out the trichomes at minimum 40x or more, 60x is more comfortable and 100x looks like an alien planet. You're at something like 60% cloudy right now, So keep checking daily because the trichomes can turn overnight . So for maximum thc as you know you want all cloudy no clear, and for that it's better to wait until you see the first Amber trichomes. A lot of the time a plant will ripen faster on the main cola rather than all over at the same time, if that's your case harvest the main first then the rest a couple weeks later. The dark period is basically so that there are less photosynthesis chemicals present at the chop which really helps with the cure, 12-24hrs is all you need, more than that you're likely to mess with the trychomes but boost terpene production. Remember though - thc production happens mostly during the cure ! The cure is very important ! The cure starts the moment you chop until the bud s humidity reaches 50%, light is a no go, try to chop in the dark and jar in the dark to preserve the very sensitive terpenes. Chop, then hang the plant whole, drying period is done when the little popcorn buds snap off the stem audibly . Manicure and jar the buds, inspecting them daily for one to two weeks (remove them completely from the jar then back into the jar again) , then weekly for the next four weeks. You can add boveda packs after the first week or two I be used the 62% ones but I'll be trying the 58% ones next. A bit more than what you asked for, but I hope this helps ! Good luck crossing the finish line ! 🚀
