Please help!!!!

PLEASE HELP!!!! I just fed my plants, week one in flower, with ff big bloom@3 ml/g, grow big & tiger bloom@2 ml/g. The problem is I fucked up big and forgot to adjust the ph. It is very hard well water. Cloudy and at a ph of 11. I use a pur water filter and it comes in around 10.2. I always add my nutes then drop my ph but I forgot. I know its probably bad im assuming i should flush, but im not sure. I'm new to the site up until now I've only read up and tried learning from others. I'm pretty new to growing. Any advice is really appreciated.

Im growing in soil. I used about 50/50 pro mix hp and miracle grow moisture control.

try setting your ph 24 hrs before you add nutes. in other words let your water sit a day before you add your nutes..i'm in hydro and my water starts at a 7.5 you can get a R.O and see if that helps but in soil it's not as important to set your ph the soil does most the work.. ph down your water let it sit 24 hrs and then test it again.. optimal ph is a 5.5 ish .. test the water that runs out the bottom of your pots and thats your true ph.. good luck well water sucks but we have to do with what we got.
KEEP ON GROWIN..

I have heard that in soil it doesn't matter as much what the ph is. But from what I know 10 is really high, and I already fed them with the unbalanced water last night and the lights just turned back on again so I know they are feeding heavy. Do I just let them ride out or should I flush that's my question really.??

if my ph was that high i would use store bought water or get a ro machine for your water supply but yes i would do a flush with a not so high ph water and start getting that ph atleast to a 7
