how long after a flush before feeding

hi guys flower week 6 and 2 days just wondered ive done a flush due to not having a ph meter as it broke i got one and it was all over the place and ive flushed to get my ph back right again and to also get rid of over 1000 ppm of nutes in my soil should i give it 4 to 5 days and let em dry out or should i feed again after a couple of days at low strength ??

In veg I don't follow with nutes usually after a flush I let them build roots looking for nutes but in flower with buds needing feeding I see why you are asking. You could have followed with a light feeding again when you flushed it could have helped with stabilizing the soil pH. Not that I recommend anymore flushing but just so you know for the future. You didn't include a photo so I am concluding you have no serious issues with the plants and therefore I'd wait until they needed watering then definitely give them nutes again.

Edit: Also we only say light feeding directly after a flush, like following the flush water. After it dries out unless there is cause we give a fair dose, maybe less than before but not light.

thanx ill just continue at like a half strength for first ones no issues really think i caught before i noticed any issues was light marks on leafs and i always check rootzone to see if its out before i think of a def so im not adding anything thats not needed as this first grow has shown with a good soil like i have its more likely locked out than not available

any advice to a newbie on how to keep it balanced does feeding at constant 6.5 keep it there or do u have to say do a 7 then a 6 then back to a 7 ph ??
