Ebb and flow - Nutrient help

Hi Guys,
I've got a ebb and flow system on the way.. should hold 5 monsters.

I've got a good understanding of how this works... however I'm not sure about adding nutrients..

can someone point me towards a resource that shows which nutients to use, and how often/how much to add?

well i like 2 different mfr's

BC products

and

Advanced Nutrients (sensi product line)

theres many good ones but BC is the easiest to use..

BC GROW
BC BLOOM
BC BOOST

You will need all 3

during vegitation you need to combine boost and grow
during bloom you need to combine boost and bloom

on the back of both containers there will be a weekly PPM chart

start with 1/4 of the reccomended usage and work your way up to 3/4 of the rec usage (i never go full strength)

make sure you have a ppm meter (40 bucks) and do weekly water changes with ro water... also you will want some calmag or sensi zyme...

i would check out the bc nutrients or advanced nutrients website for a deeper understanding...

but theres many good ones out there, those are just the 2 i use....

the calmag is a calcium/magnesium ingredient...

hydrogaurd and sensi zyme (i like the sensi zyme) keeps the roots from unwanted build up..

hope this helped
