The keys to the finest of the fine product is all about work.

You must change those hydroponic tanks every 7 days.  I know someone, let’s call him Mr P as he’s a perfectionist, who changes the solution every 1-2 days.  His hydroponic product is outstanding as a result.

Under fertilising (if you are not sure) is the way forward…once over-fertilised there is no going back with hydroponic plants.  The can detect the level of fertiliser by the depth of green on the plant.  I like a moderate green but some people go for dark dark green.  This promotes great growth but there is a distinct danger of over-fertilising and a debate wether you can flush out all the chemicals at the end.

Only careful experimentation will find the perfect EC levels for you plants, but I always recommend keep it on the moderated side.

Flushing is the final key, the longer your flush the better the hydroponic product.  I flush for 2 weeks min, ideally 4 weeks.  I have flushed for 9 weeks and the results were excellent but not effective from a cost-of-lighting.
