Simple question about FF nutes..

I've tried looking up to find a answer and didn't have much luck either finding one or just didn't understand anyone's answers clear enough. So I figured I'd ask those with the experience for a clear, simple answer..

my plant will be going on its 3rd week come the 19th, and I decided that's when it would be appropriate to start feeding it nutrients. Since I used roots organic as my grow medium, I was informed it had enough nutrients to last until then.

Now I've looked over the fox farm schedule, and I see that you start feeding your plant both grow big, and big bloom by that time.. And I've decided to start my plant on 1 tsp big bloom, and 1/2 tsp grow big based off the schedule.

My question is do I mix both of the nutrients into a one gallon of water together, or each in their own separate gallons and then feed? And if I do mix both, I balance the ph and then Feed that way? Anyone who could clarify this, it would be greatly appreciated.

Allways mix your nutes into water. And don't follow that schedule too closely or you might burn your plants. Big bloom is ok to feed often because its micro nutrients. Watch the plants they will tell you if they are missing something. I would personally not feed them yet. I understand that is "hot" soil and a 3 week old plant hasn't used them yet. Its just gotten some roots down by now. I did the same thing with ff ocean forest and grow big. At about the same age as yours. It wasn't good for the plants at all. Don't rush into things like I did.

Ok appreciate the help, so I'm def gonna keep an eye on it closely.. If she isn't showing signs of it yet, I can wait, will probably just start with big bloom once it's 3 weeks and wait and see for the grow big.
