Helps rinse out minerals and salt build up and relieves nutrient lock ups.

I took a look
its saponin which I looked up on wkipedia and yucca
its description was a little fuzzy to me... its described as glucose or sugar but derived from plants and also used for making soap... so I cant really say I understand it enough to recommend it or not
sugars are used and do help remove salts but
typical sugars are also used to increase bacteria growth which can work for you in some cases but can also work against you in a hydro set up
if your trying to feed beneficial bacteria then you add sugars but in a hydro set up it takes some work and experience that ive not had success with to use benficial (BB) in hydro
I always use sterilizers in hydro... using organic materials of any kind in the reservoir only gave me trouble of one sort or another.. I prefer to keep the organics to soil grows and or foliar feeding
but there are plenty of people out there who claim success using them in hydro
this is kinda unrelated but the floranova actually has some organic materials in it already, like fulvic acids and kelp
BB its just not something Ive had success with so I don't give my guidance on the use of BB in hydro
if you choose to go the route of using the voodoo and going the route of BB then sure use the flush if you want just don't add the Epsom or calmag with it
personally im fine with water or a weak solution and wouldn't waste my money on the flush products
