How long have you had the Tangs BTW? I dunno if it was just funny angles in the photos (again!), but are some of them on the thin side?
If so, then BONUS – incremental increases in the amount you feed is another thing you can begin before resorting to discrete fertilizers.
Don't over-feed, of course....that's a bad way to make corrections.
But increasing feeding for legit reasons is...legit! Make increases small and controlled with at least a few weeks before making any other changes....wanna see what happens each time.
