Cilantro/Coriander just got checked.
This looks like root stress with likely rot: brown, slimy roots plus shrinking growth usually means the plant isn’t getting healthy oxygen or clean root conditions. The top is still green, but the root zone is the problem child right now.
Today’s moves
Keep it gentle and reversible: check the roots, refresh the solution, and give the plant a cleaner setup if the roots are mushy or smelly.
Watch for recovery clues
If the roots stay brown/slimy or the plant keeps shrinking, it’s time to reset the setup or restart a backup cutting/seedling.
