Autoflower nutrients

Hi guys, hoping some experienced autoflower growers can give me a hand.

I have about 6 autos on the go, and i kept the two fastest growing ones inside, and the other four are outdoor, the reason being that i have such a small period of time to grow in, i cant be dealing with premature plants when i have to leave, and outdoors they can do their own thing.

The question is, what do i do in terms of a nute schedule? I'm in plagron lightmix soil.

The nutes i use are Bcuzz A+B and Bloom nutes. I'm not bothering with veg nutes because even at 1ml the plants didn't like it (recommended 1-5ml), so i'm concentrating on bloom nutes now.

The plants are 19 days old, and showed sex at around 10 days!

When should i start feeding bloom nutes? 1ml is max dose.

Could someone maybe give me a format? E.g

Week 3: (i.e now) xml
week 4: xml etc

Thanks in advance, really appreciate any advice!

I generally on autos, feed them MG Tomato, which is basically perfect for their life cycle, because they tend to veg and flower at the same time making it tricky. But here's the basic outlay of their life.

Day 1-12 -> seedling. Day 3-(20-25) -> veg, but sex will start showing Day 25-(40-45) a mix of flowering and vegging Day 40-harvest Flowering.

So basically at 3-4 weeks give them flowering and bloom nutes, but make sure if has SOME N in there because they will still be growing. Making the swap to autos is a lot harder than starting with autos and moving to photos. A lot of the feeding habits go against the grain. They don't have the same stockpile of nutes that vegged plants do.

I like to use Fox Farms Tiger Bloom after they show sex and keep that up for a couple weeks also using Cal Mag the rest of the cycle. About the last 3 weeks I'll add some Gravity from Humbolt. Got a free sample at my local hydro shop. It kicks ass. Also beneficial microbes are worth the $$ the whole life cycle of the plant.
 
Thanks for all of the help! So i'll add some n in.

As for the bloom nutes, im now at week 3, and sex has shown etc. The bloom booster is bcuzz, and normal dose is 1ml. Can anyone recommend a schedule? I.e when i go 1/4 to 1/2 to full etc?

In the format of:

Week 3: xml
Week 4: xml
week 5: xml
week 6: xml
week 7:xml
week 8: flush
week 9: flush

Paranoid about burning my babies because i can't afford a growth stunt because of the time i have left!
Much appreciated!

Since I haven't used those nutes here is what I would suggest and basically do with the nutes I use. Take the life span of a reg photoperiod plant, if you auto is NL auto for example look at how long a photo NL typically grows and get a ratio you can use to fit the autos shorter lifespan. Apply that to your autos and to be safe use 2/3 the recommended dosage to avoid burning. There is no silver bullet, and toning down the dosage until you get a feel for what works is your best bet. Good luck man!
