I can't say about soiless grow I'm full hydro. However same line. Most use Gerneral Hydroponics 3 part fluro series. I hear Sensi is very good too. I use GH but run a modified Lucas formula.

Remember all the top brands are formulated for one thing from the Amsterdam boys. All brands try to match or better each other but are close.

You will need the budblood to use in the first week of flower from then use bigbud as an add on to your nutes for the rest of flower. You really need the two.

It is best not to mix different company nutes. some times with additives you have to but try to stay all one name brand.
