Basil just got checked.
This basil does not look fully healthy: the leaves are still mostly green, but the plant is getting worse and the spotted lower leaves suggest stress from the root zone. In a hydro setup, the most likely cause is low oxygen around the roots, often the first stage of root rot. If the roots are brown, slimy, or smelly, that confirms it. If the roots are white and firm, then the next most likely causes are nutrient imbalance or pH-related uptake issues.
Do the root check today
The most useful next step is to inspect the roots and improve oxygenation if they are discolored.
Also possible, but less likely
What would prove it
Inspect roots and adjust hydro conditions
Because the plant is worsening, check the roots first. Root problems in basil can move fast, and early correction can save the plant.
