Ok ill try that used about 1/4 of espon salt to get to .3 ecyou should try weighing it out
volume and weight for dry goods is much differ

by weight I would try 1g epsom to 4g VB and see where that gets youOk ill try that used about 1/4 of espon salt to get to .3 ec
I just finished my 3rd round of v+b and it keeps getting better the more i use it and tweak to my own settings. Im in tupur under floros in veg. i noticed i needed epsom salt (not calmag) and that shaped up the veg from its mag def (ec to 1.3).
1000hps/mh...In flower i have a starting ec of .3 (r/0 plus a little residual from previous rez=.3). I then add about 150g to a 55 gal rez. to get 1.3/1.4. Once i start using the p/k boost i only use 100-120g of base and 55g of p/k to get the 1.3-1.4 ec. most varieties liked it. a few like sour d and gg4 wanted more food. I think next round i may try 1.5ec.
alright man thanks ~by weight I would try 1g epsom to 4g VB and see where that gets you
My math doesn't jive with your results, Wisher619.here is a good recipe for stock solution Epsom
158g epsom salt to 1 quart of RO water
gives you
30ppm Mag 110ppm sulfur @ 3ml per gal
or .3ec
which should give you the buffer capacity for VB to hold stable
Oh, then it is not called Epsom salt, it is magnesium sulfate anhydrous.my magnesium sulfate is 20%mag
sorryOh, then it is not called Epsom salt, it is magnesium sulfate anhydrous.
I appreciate your correctionMy math doesn't jive with your results, Wisher619.
Epsom salt is 9.8% magnesium
a quart is .946 of a liter
a gallon is 3.785 liters
math showing the addition of 158 grams Epsom per Quart:
(1/.946)10 x 9.8 x 158=16,368 ppm or 1.637% Magnesium in the stock concentrate.

Math showing addition of 3 ml of 1.637% stock per gallon of working solution:
(1/3.785)10 x 1.637 x 3= 13 ppm magnesium in the working solution

does the 30 ppm Mg and 110 ppm S include the V+B?
that must be what i am missing?....
Cheers! Might be a decent foliar recipe also at this rate also, Thanks158g per qrt
should get you
@15ml per gal
65ppm mg
84ppm S
total
149ppm = .3ec
wouldnt shine take care of this mag and suf?sorry
yoI used just RO with the RO/Soft formula. It may be of note that my R/O still comes out at around 30-40ppm(.1EC) lol.
I may try bringing up the RO to .2EC-.3EC next time and doing a stability test as well.
I wonder why even though it's an RO formula the directions on the back state to bring your water up to .3EC before you add the nutrients yet the front says "Recommended for use with all coco, hydroponic & aeroponic systems with water quality between 0.0-0.3EC" That would indicate to me that it's okay to add the nutrients to the water as long as it doesn't exceed 0.3EC
one reason why I feel that adding Mag and S is a better optionyo
I just got this stuff and am switching from gh cocotek, my tap is around 0.6ec so I cut it with RO. Having the same question I emailed the company and heres what they said:
"hi,
"i just got your v+b ro/soft and i was wondering the reason the instructions call for raising your source water to 0.3ec. would using a starting ec of 0.2 be ok as well?
i am unsure of my water quality and that is one reason i am using ro water, the water is from my well and i trust it for human consumption but i do not know anything factual."
V+B:
"You can use calmag instead. The reason we say bring your water up is so the acid buffers in the product can have something to neutralize, if there is no mineral content in the water your pH will just keep dropping. Its not an issue of our product not having enough calcium and magnesium, its all do do with alkalinity. .2 EC starting point is fine."

hope that helps,

what if your using an r.o filter... which one should you use? my water ph is like 7.4-7.8 with ro and 150-200ppmYou sir have damn GOOD tap.
I would get both and mix them. I'd say with the quality of your water you could do 75% tap formula and 25% dirty formula....and get really great results.
you might want to purchase a new ro membrane or a better pre sediment and carbon blockwhat if your using an r.o filter... which one should you use? my water ph is like 7.4-7.8 with ro and 150-200ppm
