I have just got myself the advanced nutrients sensi 2 part grow and bloom. I am a little confused about how much to give my plants. I have a product catalog and it says I should be giving 1.92ml of a and of b each week during flouring. It ays at the top 1 litre of water. So dose this mean I use 1.93ml of a and b for each litre of water I use? If not what do I do? Also it gives amounts of other stuff to use, humic acid, fluvic acid, b-52, barricade, sensime, piranha and voodo juce. Do I really need all of these cus thats gonna cost me a fortune. Im growing inside so pests wont be a problem. Thanks.

Check out the Advanced Nutrients web site http://www.advancednutrients.com/nutcalc3public/ It works it all out for you. I started with Grow A+B, Sensizym, B-52, Humic Acid, Fulvic Acid and they grew fine. Ive brought a few other bits as latewood suggested Voodoo Juice and Piranha powder. They do some mad stuff to the plants, hope this helps.

Thanks for the help, I was also wandering how much I will need? I am gonna grow 4 plants to about 4 feet high. Will one lot of each be enough for the whole grow? Will it last me more than one grow? How cost affective does it work out? Are there other more cost affective nutrients? Its gonna cost quite a bit to get all that stuff and its a lot of hassel having to get everything seperatly, are there any nutrients the have everything you need in one product?

figure how much you use each week and add that together, then subtract it from the total of a new bottle...

The nute calculator has a totals column. It should give you a general idea of how much product you will need.
