I pitched the last packet of yeast along with apple juice w no sorbate today I will take a reading tomorrow to see if there is any difference now the batch is 3 gallons of juice to 4 lbs of honey. Question how will that effect the reading on the hydrometer? Sg was 1.120 its now 1.102 since theres another gallon of juice how am I suppose to know what the reaing is meaning for alcohol sorry if that seem like a dumb question

It's not a dumb question... it does drop your SG without adding alcohol to the process because you diluted it... a ballpark estimation of your actual alcohol level wherever this finishes would be to take the amount of alcohol it produced before you diluted it (initial SG to SG when you diluted it with the apple juice starter) say it made 4% and then add that to the amount of alcohol it makes from now till it stops, (SG when you diluted it to SG it finally stops at), say it makes 10%, estimate it at 14%.
This won't be entirely accurate and there's a more accurate way to calculate it that involves more math I'm too lazy to do, but then I don't know precisely how accurate it is to calculate alcohol content from change in SG anyway (I don't think we account for the ethanol produced, which will bring the specific gravity down because it's got a lower gravity than water)...

Thx for the response I was never good at math. I took another reading its now showing 0.92 after the extra gallon of juice. it reached a abv of 2.22 percent when it was the original batch and sg reading which was 1.120 final reading before it was diluted was 1.102, now its diluted with a reading of 0.92 all i know is i be confused on the acrual abv it will create and also now isnt a wild guess as when it w actually be done fermenting from the reading.
So is it fare to say that the new reading is the sg and when it stopped to add that abv with the abv it had after adding the new juice n yeast?

Yeah, pretty much. Pretend you're dealing with a new batch starting at 1.092 that already has 2.22% alcohol... when it finishes, take that SG and use it with 1.092 to determine the new amount of alcohol produced, then add it to the 2.22% you knew was already there.
