Mixing Steps / Procedure?

Hello,

Using Advanced Nutrients

Is this the right procedure/steps?

1. 3 Gallons of good tap Water
2. Add Seni Grow (or Bloom)
3. Add all other nutrients
4. Mix and shake
5. Wait two hours
6. Check PH (adjust)
7. Water plants

..... IE: Checking PH after waiting 2 hours or before? I am waiting 2 hours because I was told this is best.

Many thanks.

Mix between each item.
Wait 5 minutes, adjust mix, wait 1 minute, repeet.
Always check nutrient ph before each use.
Don't make me get abrupt.
