Nutes Question General Hydroponic 3 Part

ok i have got the 3 part general hydroponic nutes but is this all i need or do i need more like trace elements that iv been reading about?

most likely you will not need trace elements as the 3 part contains all of those trace elements, mostly in the micro. however, if you're water is fucked up, this might cause you problems. and by fucked up i mean hard water with lots of dissolved solids.

Take a look at the chart http://www.eurohydro.com/pdf/tabs/gb/fs-aero.pdf and see what can be used. I use 3 part also and have added the diamond nectar and bio bloom. The roots kick off when you use nectar and the bloom made my girls look perked...and then you can read FDD's post https://www.rollitup.org/outdoor-growing/24703-its-all-bullsh-t.html lol thread with nice pics!

its hard to get a decent crop with GH3 parter without also using cal/mag plus. ive been using GH for yeras now and can really tell the difference when i use the cal/mag with it.

i dont know if the water is hard but hopfully it aint ok well i was gonna buy diamond necter but it costs a tone and dont have that much cash atm i think i will stay with just the gh 3 part as long as the pant wont die from it and then buy cal and mag or diamond necter if im feeling rich lol thanks all

what kinda calcium and magnesium products do you use, my plants are almost 2 weeks old and are 4-5 '' tall, is this a good time to start the 3 part?

ok well just went to buy cal and mag but got zinc and mag by accsident can i still use it or will it give it to much zinc?
