With a likelyhood, bordering to certainty, the lightest blade has the centre of gravity the most outward, and the heaviest blade has the centre of gravity most inward.
In that case most likely there is nothing to worry about.

If you want to know for sure: Measure of each blade the exact weight, and the exact distance from the rotorshaft to the centre of gravity of the blade.

Calculate for each blade "distance multiplied by weight" and this figure should be equal for all 5 blades. If that is the case, the blades will be in balance when fitted on the head.

For example, a blade weighing 40 grammes exactly and having a CoG distance of 250 mm would balance with a blade weighing 39.5 grammes and a CoG distance of 253.2 mm because (40 x 250)/39.5=253.2

Mind you, you need to use the distance from CoG to the centre of the rotorshaft, as fitted on your rotorhead, NOT the distance from hole to CoG
