Earth Juice hydro nutes!

I have been growing indoors for a year now(4 soil grows....nothing special, northern lights and Ice mainly) and have decided to go hydro.

I have already purchased Earth Juice nutes.....grow and bloom, catalyst, and micro blast.

Do I really need Meta-K?

Also, I do plan on getting Liquid Karma.....heard the stuff is kick ass.

Any other supplement/nutrient that is needed?

earth juice is messyy i tried it in a DWC setup once and it did not work out at all LOL started foaming everywhere leaking out of the buckets

You will have a hard time regulating the PH.I dont know anyone who uses earth juice in hydro,Its great for soil.Buy the advanced nuts Iguana, juice if you want organic ,its PH balanced. If I was going hydro Id go with the 3 part advanced nuts its cheaper and works well in soil too I clean that fucking soil up every 3 months and have nowhere to dispose of it without being seen.I tried hydro its just not for me
