Feeding question - will +rep

Hey all, I'm in my first week of veg and ready to start feeding my plants the Humboldt nutrients line but I had a few questions. Feel free to call my questions stupid but I'm trying to be safe as this part of feeding isn't quite clear to me.

So I have Humboldt Grow, Micro, Bloom, Equilibrium and Verde. My question is not how much to feed, but what exactly to feed...

Am I just using ONE of the above at a time or am I making a mixture of a few of them combined? The last thing I want to do is get creative and start mixing up a deadly concoction of 2-3-4 combined nutes.

+rep for any help! Thanks!

Here is their feeding schedule http://www.humboldtnutrients.com/feeding-charts/#Conventional

...week 1 of veg is a little early to be adding nutrients...

You can buy a 60ml measuring syringes for around $2 at most hydro stores. I like Discount Hydro only because they have a store 20 min away from where I live.

Did any of you actually read my post? LOL ugh... luckily a friend helped me with the question and I didn't have to solely rely on RIU.

The right answer, mix everything together!

make sure to mix it in the water and not premix chemicals to avoid nutrient lockout.
