Need help introducing FoxFarm Lineup to my 2 week old plants

Hi everyone this is my first time growing and I'm on my second week on plants and wanted some help on how much to give them and how do I go about mixing them if possible I'm using pretty much the whole line up of foxfarm with the exception of about 2 products or so.

My plants are still in plastic cups going to transplant in another week or so.
They are in foxfarm light warrior soil that's all
When transplant I was going to mix 1 bag light warrior 1 ocean forest 1 perlite
Looking at the ff feeding schedule online it says I can already use the Big Bloom & Grow Big. Also it says I'm able to use the Kangaroots & Microbe Brew.

My next question is can I mix them all at 1/4 dose in a 1 gallon jug of distilled water? Or do separate batches? Because it seems like a lot of jugs for my 9 plants in cups. Also when watering do I water enough for runoff? And test that. I got a ppm meter and ph meter as well.

Really need help about going about this lots of questions I have and don't want to mess this up if you can give me some advice. I've been on youtube and forums but just leads me to more questions.

Can I use those 4 products now or wait some more. I've just been watering with distilled water.

Just would love some help about doing this
Can post pics on whatever you need to help

Follow the Fox Farm feeding schedule. I started feeding with Big Bloom 3 days after they cracked soil, and the babies are doing great! I am feeding at 6tsp per gallon of RO water.

And I am using Fox Farm Light Warrior/Ocean Forest/Perlite at a ratio of 4:2:1

Same nute line up here, I been using it for 2 years now.Except I only use light warrior for solo cups. And I use promix, happy frog and ocean forest (good for about repotting into 10- 5 g pots).
I wont always follow the 1st few weeks on the schedule unless they look like they need a boost. The reason I dont feel like I need to follow it is because my soil is packed with nutes and I dont like buying BB and GB every week (watch how fast those 2 bottles get empty feeding twice a week) I didnt notice much difference when using the feeding schedule from wk 1, to just using it for pre flower treatment starting on wk 4,which is the old method for FFf schedule. If youre going to follow the feeding schedule from wk 1 make sure you are timing your dry outs to meet that feeding time. I dont always have run off, but I make sure I do for the flushes. Good job not getting flowers kiss, shit sucks.
