I was wondering when it is best to use the flowering nutes. Is it a week or two Into flower or as soon as i switch lights to flowering?

You should start using the flowering nutrients (Bud Start, Carbo Blast) week 2 into flower.

How often should I use Bloom?

Please refer to our feed schedules under DOWNLOADS for accurate information (https://futureharvest.com/pages/downloads). You should be using Bloom every feed but feeding frequency will depend on your plant and growing medium. We also recommend a straight water flush every third feeding.

If I water my plants every two days , do I have to water my plants with no nutrient s between each feed or I can just water with nutrients every 2 days

We recommend a straight pH water flush every third feeding! (Regardless of days). Best practice is to monitor your plants and know what is best for them.

How much bloom do I use in a 5 gallon bucket

The ratio changes depending on what medium you're growing in and what cycle your plant is in. Please refer to our DOWNLOADS page for accurate measurements. All measurements are in mL per gallon.

I have mixed up a batch for a water change. And I would like to add more nutrient to raise the ecc a little. Can I just add additional fertilizer one at a time ?

Hello Shannon.
Have you been feeding your plants our nutrient line up since the start of their growth?
You could add additional ferilizers, but you need to be cautious over your pH and PPM meters. 
Thanks for showing interest in Future Harvest Nutrients.

Do I combine measured amounts of all 3 nutrients with 4 litres of water

As indicated by our feed schedule, one by one, add each measured amount into your water. Remember to always mix Micro and Calnesium first to minimize the calcium falling out.

Does this nutrient line contain pgr's?

No, our nutrient line does not contain PGR's.

If I am using dirt to grow my plants are the measurements the same? Thank you
