Start with the liquid additions. Food Network ranch recipes explicitly use buttermilk to adjust consistency, so the fastest question is whether the dressing crossed from creamy to watery during the last buttermilk addition.
Symptom matcher
Which one looks most like yours?
Small visual differences can point to very different causes.
Check the buttermilk or water amount.
Check the base ingredients.
Check vinegar or lemon juice.
Chill it before changing the formula.
Check for water on the herbs.

Can it be saved?
Usually.
Limit: A heavily over-diluted batch may require enough extra base ingredients that seasoning must also be rebalanced.

Get to the first clue faster
Answer one question at a time. The result comes from the same reviewed diagnosis data below.
Did the ranch become thin immediately after adding buttermilk or water?
Was the mayonnaise-sour-cream base already loose before that?
Is the dressing unusually sharp from vinegar or lemon as well as thin?
Was it judged before a proper refrigerator chill?
Reduce the thinning liquid
The final buttermilk addition pushed the ratio too far.
Likely cause: Too much buttermilk or water was addedUse a thicker creamy base
The dressing started from a loose foundation.
Likely cause: The mayonnaise or sour cream base was unusually thinReduce excess acid
The acid is contributing both liquid and sharpness.
Likely cause: Too much vinegar or lemon juice was addedChill before changing the formula
Freshly mixed ranch can firm slightly when cold.
Likely cause: The dressing has not had time to chillDry herbs and add-ins
If the ratios are correct, carried water from add-ins is the remaining likely branch.
Likely cause: Fresh herbs or wet add-ins carried extra waterDiagnosis
Check the likely causes
Start at the top, but skip anything that clearly does not match your batch. Evidence labels describe the support for each cause, not a fake probability score.
Too much buttermilk or water was added
The dressing became thin as soon as the last buttermilk addition went in.
Compare the amount of buttermilk used with the mayonnaise and sour cream base.
Whisk in a little more mayonnaise and sour cream in the same ratio as the base.
Add buttermilk gradually and stop at the desired consistency.
The mayonnaise or sour cream base was unusually thin
The base mixture is already loose before buttermilk is added.
Compare a spoonful of the mayonnaise and sour cream with standard full-bodied versions.
Add a thicker base ingredient gradually if flavor balance allows.
Use a thick mayonnaise and sour cream base when the recipe is designed around them.
Too much vinegar or lemon juice was added
The ranch tastes sharply acidic and is also thinner than intended.
Compare measured vinegar or lemon juice with the recipe.
Balance with more mayonnaise and sour cream rather than adding more dry seasoning alone.
Measure acid and adjust after the base consistency is established.
The dressing has not had time to chill
The dressing was judged right after mixing while still relatively warm.
Chill a small portion for the recipe's stated rest and compare consistency.
Refrigerate before deciding the formula needs correction.
Judge the final texture after the planned chilling period.
Fresh herbs or wet add-ins carried extra water
Thinness appears after a large amount of freshly washed herbs or other wet add-ins are folded in.
Blot the herbs or add-ins and note whether free water is present.
Strain off visible free water only if practical, then rebalance the creamy base.
Dry herbs and other add-ins thoroughly before mixing.
Don't jump to conclusions
Common misdiagnoses
Kitchen science
What is actually happening?
Ranch is a cold emulsion and dairy suspension rather than a cooked starch sauce. Its thickness comes mainly from mayonnaise and sour cream, while buttermilk, vinegar and other aqueous ingredients thin that base.

What we plan to test
Planned tests are shown transparently and are never presented as completed results.
Ranch buttermilk-ratio comparison
Increasing buttermilk while holding the mayonnaise-sour-cream base constant should make ranch progressively thinner.
