So simple makes me so numb ..

OK this should be easy for you guys ..
Basic fert mixing question i will include a pic of my ferts directions .
it calls for .37 fl oz to a gallon . Well m not sure how the hell you measure .37 when no measuring device goes that low so i try to use a converter only to find it wants to know if i'm looking for us or imperial i see there is a big diff in the numbers . I was told i had fert burn so i'm trying to figure out where i went wrong .
if some guru can tell me using a normal mixing shot glass what i would be looking at for A 3 gallon mix .
this is for dwc set up.

Got anything to measure 10 milliliters or cc? Or 2-1/2 teaspoons.

3 gallons is 11.4 liters, so with 30ml/10L, you're gonna need 34.5ml.

ok still confused

that's way more than i was using and i was over ferting according to our local store / growers.
but when i ask other questions i got sorry we don't do hydro we grow in soil

show us your plants. Who says they're experts just cause they sell the shit? a 2nd, 3rd, 4th opinion cant hurt.

Thats what I told him but he said he's got nute burn from less than that, which I don't necessarily agree with.

Maybe he thought you meant per gallon?

Maybe, although he did state it was for a 3 gallon mix. We shall see! either way his plants dont look too bad.

I was mixing using tbsp and thats came out to over six i went with 6 . leaves were getting cooked on the ends , edges i talk to them they say to cut back i do that now i see yellowing all over today . lights just came on so i got to look .

A look at the whole plant

I don't know anything about it, but the yellowing could be lockout seeing as how you are getting nute burn, also only affecting your new growth so far.

I'm just spouting things I've read from leaf problem pages.
