How to get soil PH to 6.5 PH water runoff?

I gave my early candy 6.5 PH nutrient mix with water. An the run off came out at 5.0 PH. How can I get my soil PH stabilized?

I got two choices. I can PH nutrients mix to 7.5 PH. An feed that next time. To raise the soil PH. Or I can flush it with extra water than normal with 6.5 PH water no nutrients to get soil PH at 6.5. Doesn't seem to be working I only barely started checking PH though cause im a lazy ass.

You cannot adjust soil ph with water, at least not quickly. The ph of your soil has a strong signal that will always out buffer the weak signal of water ph. Soil ph should be determined and stabilized prior to growing.

I added dolomite lime as a buffer

What kind of soil ?

Fox farms ocean forest I'll get some pics soon.

Ok .....

FFOF is already prebuffered to 6.3 .... it is very nute heavy by itself , so much you can run alone for weeks - On Water ..................... adding Nutes to this already hot mix causes issues.

I run it on ph water 6.5 ( adjusted ) only for up to 5 weeks before any signs of depletion.
There is no need to check runoff .... your excess nute addition is overpowering medium.
Straight out of the bag it is buffered with oyster shell .

I forgot to exact day around 4 weeks. I wasn't feeding for first two weeks anything. An started using Dr Earth starter fertilizer. My plant looks fine it's just my PH is off it's younger than my other three plants. My other three are getting nitrogen deficiency. Im need something for them. The top pic is the only one with PH medium 5.0 PH runoff.

Went thru this hassle when I first started to grow and bugeye is right it's not easy trying to raise soil PH especially hot soil like FFOF. Dolomite was a smart choice to buffer the soil but unfortunately it needs to be mixed in the soil pre planting (and it needs to sit in the soil for some time to condition it) applying it on top won't be very effective but won't hurt. You can try flushing the hell out of them but your going to stress the plants by water logging them and flushing a lot tends to pack the soil.
So what I ended up doing (because it was going to be a loss anyway if I didn't do something about the PH which could drop as low as 4. (home made soil) was to give them a one time flush with twice the water of the pot size and put thru a very High PH solution every time I watered after that (sometimes as high as 9 because well, I had nothing to lose) Eventually the Ph came around (low to mid 6's) to where the plants nutrients were no longer locked out (which is why your experiencing nutrient deficiencies) and they did recover. If your still in veg it shouldn't be that big of a deal if there're in flower it's really going to piss the plants off but they should come around.
I can't say this is the best advice because at the time I didn't really know what the hell I was doing but just had to do something to try and save the crop and in the end I got a not bad harvest but learned a great deal about soil prep and conditioning and the next crop was a helluva lot easier.
GL!

@WeedZen I added dolomite lime pre planting and I didn't let it sit I figured it got 2 weeks to sit will seeds we're sprouting

Your pots are dried out, and are too small (3 gallon minimum?)
You should never see a gap around the edges of your container or pot when your soil is dry, which it should never be.
Listen to Bugeye, amending FFOF for PH is not gonna happen, it's already prebuffered.
Simply feed your plants with water adjusted to 6.3, and all will be good.

Dolomite takes months to break down and stabilize.
What will work is Hydrated Lime, which is very rapid in adjusting soil PH for a 3 month grow.
I wouldn't worry too much about your soil PH in FF, it's stable at around 6.5, which is really as good as it gets for dirt.
Worry more about your seeds and lighting.
Happy Holidays!

Im growing 3 small dwarfs and one photo cross auto. I thought 1 gallon pots is all I need for small autoflowers. Although im in half gallon it's all the room I got limited to space and height. Thanks everyone for your tips. Im going to water today just letting roots breathe a little before feeding or watering
