How Much nutrients do I use in a 19Liter bubble system

Hi all, I'm new here and I'm new to hydro and looking for some pointers..

I have a 19 liter rubber made container for veg and blooming into.. I want to keep them small no bigger then 1 foot fully budded..
I am working with just tube lights thats why.

I have a question about the nutrients i'm using .
I know it says;
1.25ML per liter of ( A )
and 1.25ML per liter ( B )

but thats a total of 47.5ML with (A) & (B) together, it just seems like alot for 19 liters of water..

if this is to much can you explain why and tell me what would be better... I have taken a photo of the feeding schedule ..

thanks for all the help.

Note; I'll be putting in 6 clowns in it. I think my system is called a bubbler becase there is just air stones bubbleing at the bottom.

bump... bump...

Yo yada i would start at quarter strength and build it up from there.also make sure you cover your tub and lid to make totaly light proof stop any nasties growing in your rez and keep your water temps at about 64 no higher than 72 or you could get root rot.hope this helps

Bro, that's really not a whole lot. 1.25mL per 1 L. That's 1.25 mL per 1000mL. That's a ratio of 1.25:1000. VERY WEAK mix. Remember, in DWC the only nutrients the plants are getting is what you give them. There isn't anything for them like there is in soil.
