Which type of blooming nutrients?

I have six plants in my hydro system i got from stealth hydroponics. I have nutrients that came with it but should i use some other bloom nutrients? I want to have the best harvest i can in my first grow! what should i use?

Not sure exactly what nutrients come with your system, but yea, if you want to get the most out of your grow, bloom nutrients will help you get there! It then depends on whether you are doing organic or not. If you are growing organic, I would recommend the Canna bloom boost. It is pretty expensive, but it is the best you can get. Just make sure you cut back on your regular nutrients if you bring in a bloom nutrient, as the ppm will increase. Typically as you get closer to harvest, you will start using more bloom nutrient and less of your regular fertilizer

It isn't organic. I grow in rockwool. I have this one...http://www.stealthhydroponics.com/product.php?xProd=121&xSec=64

Use up the nutrients, do some quick math to see how far the nutrients provided will get you. If they are sample size, they wont last long and a nutrient change up can cause stress to plants, you should be ok either way. Buying a more reputable brand nutrient may give better results, i am not familiar with the nutrient shown in the link provided.
