Before you buy any fert do yourself & your wallett a favor & research fertilizers & how they are made,all the info you need is in google & easy to locate,an hours research will show that there are no majik sauce ferts & that expensive botique ferts are no dfferent than ferts costing $3 or less,spending $25 or more on ferts is not needed nor does it offer any benifit other than the buyer having a good feeling from buying a premium product.
Fertilizers are made from salts,some ferts are made using inexpensive salts which lead to a hot dose fertilizer (Miracle Grow) where it is easy to roast a plant while other ferts are made with top quality salts which makes a much more user & plant friendly fertilizer that wont burn,fox farms & other botique companies use the high quality salts but you better lube up well for the ass pounding they put on your wallett.
As a testament to the unnessacary expense of these ultra expensive fertilizers try & find testimonials from one single farmer, or commercial produce grower as to the benifit of these small time ultra high dollar botique fertilizer/soil marketing operations,farmers are businessmen & any product with the ability to enhance yeild would be looked at very seriously,keep this in mind when others reccomend botique soil at $25 a bag,a little research on what weed plants need from soil will reveal that a proper soil perfect for growing weed can be made using off the shelf soils & soil amendments from any home depot or lowes at 1/10 th the cost.
The same quality ferts can be had for about $5 in several off the shelf ferts,i use Peters granular fertizers exclusively,i used their ferts for years while i was doing indoor soil grows & had spectacular results that were just as good as the results from Fox Farms products,ive converted from all soil growing to all hydro growing using flood & drain tables over a year ago & have used Peters brand in both hydro & soil.
When i 1st went hydro i ran fox farm fert till i mastered growing flood & drain then switched right back to Peters ferts with equally high results,after researching ferts look into Peters brand or Jacks Classic brand ferts as they are both the same content from the same manufacturer using only top quality salts which are also full range ferts containing all the micro nutes that several botique operations do not include.
