Ok...first off Hesi's directions are for an AGGRESSIVE feeding routine.. In many years of use I have found that for the most part their's does work and well, but you must know that they are using 3 gallon or larger pots. indica's and some hyb. work very well with the aggressive feeding but I feel you should have a good knowledge of what your doing to run that.
Next, power zyme is NOT snake oil! and should be used. It contains the very useful MICRO NUTES!!! that are NOT in the other Hesi nutes.... In fact Hesi zyme has now been voted and tested out as the BEST zyme on the market!
Use CALiMAGic for RO suppliment before you add nutes! 3ml per gal is what I run.
A quick note on advanced nutes. RIP OFF!!!!!! they have 3 diff. suppliments that are the exact same thing at 3 diff. RISING prices!!!
and BUD CANDY is one of them. I use Botanicare SWEET UNFLAVORED. What this MAG&SULFER suppliment does is increase the tricome and terpentene levels in your finished plant. IT WORKS!
I do my Hesi runs like this. VEG
use the listed concentrations of TNT, POWER ZYME and SUPERVIT (the vit contains needed amino's that help your plant with growth regulation and overall health levels....NOT SNAKE OIL....Look at House and Garden,,,,they use a stand alone amino and it works! Hesi just contains extra B vits along with the aminos)
ONLY USED THE ROOT COMPLEX 1 to 2 times a week!!!!! ( I use it once every 4 days)
FEED EVERY OTHER DAY! unless you are running the aggressive listed use.
I use MAD FARMER silica at a rate of 2.5ml per feeding to up the cellular strength of my plant. It also allows the plant to tolerate higher temps that are associated with the use of CO2 in flower.
FLOWER
at change over I drop all use of ROOT COMPLEX.
Run the stated concentrations of BLOOM COMPLEX, SUPER VIT and ZYME -
and drop the CALiMAGic and start SWEET UNPLAVORED at 5 ml per gal for 1 weeks.
At week 2 up the SWEET to 10ml
AT week 3 up the SWEET to 15 ml
At week 4 begin the use of PHOSHORURS PLUS at stated Hesi levels and drop the silica use to 0.
At week 5 up the SWEET to 20ml and begin adding 1 tsp of unsulfered molasses continue this till wash and you will be beyond happy with your crop!!!!
As far as hydro go's I feel that Hesi is far and away the best nutes out there for that application! SIMPLE , CLEAN RUNNING and just use as directed ,,,,, You may want to lower concentrations for pure sativa's by 25% at first try......Better yet you should run sativa's organic in dirt , using a tea!
I HIGHLY suggest using MAD FARMER up and down as it contains a better more stable mix of chems and has NO DYE in it. (be careful as the down can be twice as strong as all the rest of the downs on the market)
Grow on and enjoy!
