Yellowing problem? Or normal?

Mandarin sunset in a 5 gallon smart pot with nectar of the gods nutes (feed feed tea feed feed flush) she has had two “early flower” feedings and a microbe tea the last 3 feeds, before that she was getting “late veg” during feeds. 10 days into flower, watering every 48 hours roughly 1.25-1.5 gallons to a slight runoff. Every day or two she’s got a few leaves like this, sometimes they’ve dropped othertimes they’re just barely hanging on and a slight bump knocks them off. Other than this she seems super healthy, is there something wrong or is this pretty standard? They’ve all been below the canopy line. This is my first grow and I would hate to ignore something after this long

try a feed water feed tea water feed water feed feed water tea water feed water feed water .

plant looks like its just dropping the extra baggage it doenst need in the lower parts. Weak lights maybe. could stand to get rid of a few of the largest leaves to get some light onto the lower bud sites.

Plant looks to be cannibalizing lower leaves that arent getting enough light.
Normal since they are sitting under a dense canopy.
Nice and healthy looking imo.
