Look like you have put a lot of planning into the layout of the emersed setup. Quite natural looking.
Hydroponic is simply soil less growing.
Technically speaking, planted tank using gravel, flourite, non nutrient absorbing clay based substrate, inert substrate is hydroponic.
Things like anubias, ferns, moss growing on wood can be logically group as hydroponic growing.
plants can absorb nutrients through the leaves, rhizome and stems.
From looking at the coffeefolia, I agree with green this is a Mg issue.
Looking at the Buce, and the yellow anubias(?) also point to Sulphate issue. The leaves look rather pale for new growth.
Do you do any water change? Do you test for pH and nutrient concentration?
You can do weekly 100% water change and use a 1 dose approach EI method right after each water change.
