gold label hydrocorn

after 3 succesfull grows in soil i decided to try gold label hydro with a dripper system but i cant find info on which nutes to use.i used canna terres with the soil to good effect and would like to know which nutes i should use with this media plzzz. id like to stick with canna but do i use hydro or can i still use the terra with these pebbles.
also how do i tell what ph the pebbles are as it says i need to adjust this before planting.
sorry for the newbie question but i cant find info on the net.

For hydro you are really going to need both a ph meter and a ppm/ec meter. You will also need some ph down. Get some low ppm water and soak the hydrocorn in ph adjusted water. For nutes I use General Hydroponics Flora series. Just starting off you want to keep hydro as basic as possible. I can't cover it all in this thread. I recommend a single General Hydroponics water farm which contains everything you need to get started in hydro including nutes (but not the meters) This will help the learning curve and set you on the most direct path to success with hydro.

I thought canna makes nutes for hydro. I use blu moon I don't know where you are but I'm sure your local groow center will have a slection of nutes you can use.

my water comes out of the tap at 6.5ph.i only use ph up/down when adding nutrients. i didnt really want to go to the expense of buying new nutes as i have 5 blue mystic growing in soil still in my tent.
on the subject of my local hydro shop.we had a conversation about canna boost versus molases and even they agreed that mollasses has the sames ingredients as canna boost.
thanks for the replies chaps.this is all new to me but id like it to be as, if not more succesfull than my soil grows.
