Drooping moist lower leaves, am I overwatering?

Necesitas un transplante (la maceta se ve pequeña para ese tamaño de planta) o hacer poda de bajos (lollipoping) como te han indicado los compañeros Controla también el riego! No vuelvas a regar hasta que la maceta esté "seca" y no le pese el culo.

Hello, I looked at your video and your nutrient meter, and I would suggest transplanting the plants as soon as possible. I compared the amount of nutrients you used in past weeks and it seems like you might have added a bit more than you usually apply. Also, the leaves are on the darker green end, they are wilting, and the curl seems a bit mushier than they look when their rootbound, indicating to me an access of water or something, like the over application of nutrients your diary says you applied, when compared to previous weeks. Try not feeding anything for two weeks, let that soil and those roots dry up, when you feed again, just use just water for a week or two, as the plant's roots are likely burned a bit.

Can be a sign you need to lower the plants energy output to better suit its input Also. You're very far away light wise. This can also play a part. As static led light grows this can happen Plants need rotating, good LST and good airflow through the structure to support exchanges on a molecular level at the stomata layers. As they're like vents that excrete o2 in exchange for co2. And if you don't have good airflow over these leafs they have difficulty breathing ie droopy, less life/vigor and overall slower growth. And will eventually die to co2 starvation from poor ventilation. I've been reading up a lot about co2 and stomata layers.. it explains the affects of not exchanging these layers and expelling the lighter o2 for co2, its an exchange and ven is key.

Looks good maybe a little overwater but also notice the tips are curling downward like pushing the nitrogen a bit too hard

shielded, older leaves, also a fairly small pot relative to the plant at this point. Soil, so that's probably part of it too. a plant starts to neglect leaves not pulling their weight (shielded or aging out). it'll start to shed them. Some of that looks like it's not getting water. i'd clear out all the stuff in cenral lower area of plant. prune it off. if any bud sites look like they are 2 hairs and nothing else, i'd pull that off too unless you intend to make hash or something with it. only at lowest, most shielded areas.
