I will say since I started using both my Brix levels (sugar in the sap) has gone from 10 to 15 and that is all about the roots so I have to give credit to the Tribus and the Lumina. Pricey, yes but worth it, it looks like it
have you tried the floraflex nutes cpw. im running that in my new setup with great results.also a little pricey but easy to use.
