Question about house and garden nutes

I'm going to be growing in coco soon and am going to use the house and garden line. There are so many additives in this line it is crazy. I would like to cut cost and only use what is really needed but still try and get the most out of it.
So with this I'm probably going to buy these products because they seem to be the framework behind hg line:
Drip clean (I'm using tap water 200ppm)
Coco a and b (deft going to need this)
Root ecelerator (I've heard nothing compares)
Bud xl (I've used it first hand and all I have to say is wow)
Shooting powder (awesome stuff)
Magic green (I got it for free so I'll be using it once in awhile). V

So do I really need algae extract, top booster, amino and multizen?
im thinking about buying a few but I just don't which one and if at all they will help? Maybe some of u professionals can help me out here? Are these extra nutes worth it or are Ed just marketing tactics after everything I've already bought?

Hmm no answers?

The drip clean is not necessary, I use 280ppm water and I don't get any deficiencies/lockouts ever. Growing in coco hempy now and it is like a problem free DWC.

Edit: I don't know if all these additives are going to help you very much compared to the costs. I use only Coco A&B, liquid silicon and Pk 13/14 and grow some nice buds. So I don't really see the value in buying any more.

I'm feeling the same way but the root ecelerator looks promising. At my local hydro shop they showed me roots on a tomato plant with and without and I was amazed. But sometimes u never know they could just be doing it for marketing. I mean I wasn't there when they added the nutes yano
