As many will say, they live in water so no overwatering. Lol

5.8 ph for veg and 6 ph for flower.

Run however you like but I have found 1.2ec has been very stable for me , running on the air we breathe. No co2 enrichment.

Hydroguard is watered down bacteria, if you choose live I would suggest Hygroben instead.
1 cheaper
2 it’s way stronger
3 more than one type of bacteria.

And if you choose death, which could be very good I would suggest hypoclorous acid.

Enjoy and good luck

What's your EC?

This is speculation but "upped the nutrients" in combination with even a slightly high vpd might cause a drop in osmotic pressure from the roots so you see some droop.

The atmosphere might be pulling water out of the plant faster than the roots can replace it because the salt gradient is too high. They have to pump their own roots full of more salt than what's in the rez to get water to move across the membrane. If the rez is high EC, the plant has to do a tremendous amount of work to make this happen.

Early in life without the benefit of more leaves and roots, and usually under subdued lighting, it's asking a lot of them.

So...rant over lol. What's your EC and vpd again?

vpd
1.48
ppm 600=660

1.48 is good for late flower, try to bring it down closer to 1 and see how they do.
