Oh that. I didn't even want to mention it. Slight over watering. That is why I moved to inert media, coco coir and fired clay balls. It won't hold water or food.
I can have timers and get the root ball within the first couple of weeks from clones to begin taking feed every day. For example, I am conditioning a couple of them now for 2x a day feeding. But, it is a process. I have a couple that I'm working into 1 x day.
What happens is even in fully drained media, the second watering is too much, and the symptom is that. Drooping leaves. Technically (I just checked to make sure this is the advanced section) it is transpiration that moves fluid up the plant. The pressure difference from evaporation and other uses, draws up water. So, that really helped me to see that we don't push water into this plant. It drinks water as it pleases. And the only way it can do that is through transpiration.
So, if there is too much water suddenly, and you can see this in most plants, the transpiration elevator gets swamped literally. The leaves get heavy and droop, in that fat healthy way. That is OK, for say a big rain. But, roots that are subject to too much water and no transpiration are not really functioning well. They get thin and meager, all that.
Don't worry, way out from where you are, but I have performed hideous experiments.
The last picture, your stem is thick and green. You don't want thin and dark/hard main stalk. Most of the aspect is up and happy, with some leaves heavy. A little water withholding, will perk that right up.
For the color. Good.
For the lower leaves the girls will tansport that nitrogen to the bud masses. But, it means they could use a bit more nitrogen, since you are so early in bloom. Later in bloom you will see this more. Natural.
Hope it helps.
