I dont think its dangerously yellow. Still, calmag with some iron in it could help with that yellowing.
I'm especially subbed to see even chinese leds can grow good shit.

Some friendly thoughts. You don't need a lot of light or 5gal of water for plants that small (assuming that's a 5gal bucket.)
If you want to run a DWC mom you can do so in a smaller container at a tradeoff of having to water more (gain some space)
I run some moms in DWC (ha not quite) in containers as small as 28oz peanut butter jar with 2" net pots. If you want to increase what you can do in that space I'd look at decreasing the size of that reservoir.
10-20W of cheap LED will keep a small mom (plant that size) plenty happy until its time to take cuts.
Some yellowing on tops in early flower is normal ime you might make a slight increase in feed rate or frequency or let it run as is as it doesn't look totally deficient yet. If you're still running distilled water that might be the source, you're lacking the macro/micro found in tap.
for seeds off of wish im impressed lol....
id love to hear a smoke report etc honestly.
