Could you tell the two best nutrient combos for hydroponic vegetables and herbs?

My two favorites are House and Garden www.house-garden.us (Highest quality and cleanest in reservoir) and Bio Bizz for 100% organic www.biobizz.nl (organic Hydro gardening can be a little more tricky).  The reservoir always gets more “mucky” with organics.  This usually involves more maintenance. I hope this will help in your decision.
