Don't know about the master part, but somehow it always works for me. Mother Nature likes me, I guess! I forgot to mention, if you need to go out and buy a small bottle of that liquid fertilizer, you might as well get the version that has trace elements added. That will be shown on the side panel of the little box. There's very little difference in price. Also, make sure the number in the middle is the highest such as in 5-10-5. That's the one that's going to GROW STRONG ROOTS FIRST. In a couple months, a change over to 10-10-10 can be done to BOOST GREEN GROWTH, SECOND. Time release fertilizers are not recommended the first year.
