Ok I feed my plants and the 2 biggest have a really low ph problem..4.4 and 4.5.

Well i know that you can use baking soda to raise ph in soil. The PH was good going in but run off was way low.

Should I mix up another batch of food and adjust Ph or do I use plain water. I dont know if I use water if it will wash out the nutes I just feed them. all my other plants are fine just the 2 have a ph issue.

dont know if it matters but I'm using the FF 3-part nutes, and distilled water.

Another ? while I'm at it. Am I wasting my money by buying distilled water compared to tap water that has been set out for 24-48 hrs?

Thanks guys/gals

Well Knottyd, you have two excellent questions.

So far as your ph problem, I think your problem arises from when you are taking your ph sample. I use foxfarm too, and it can lower your ph to as low as 3.5.
At question here is whats in your soil to buffer this?

To properly test and adgust for ph in soil:
add your water and nutrients to your watering pitcher, & feed your plants, dont worry about ph yet.

Water til you get a fair amount of runoff, and test this!

If your results show a ph of lets say....5.2, raise your ph x1, prior to feeding to raise it to 6.2

Do not test your water, or your water and nutes, always test your runoff.

Some domolite lime will help in buffering your soil better.

So far as tap water vs store bought, this is a debate that has plagued us for ages.
You dont say if you have well or city water but, if it were me, I'd be using my own water, and saving my money for a R/O filtration system.

I hope this helps your grow.
Peace

Thanks video,
What I'm using for soil is a mix of perlite, vermiculite, and peat (1/3 each). I only check the run off, not the soil. My question mainly was if my ph is low do I fix it right then or readjust on the next watering and if I fix it right then do I adjust it with raised ph water or nutes with a raised ph. I'm just not sure if rewatering to correct ph will 1) casue drooping due to overwattering 2) wash out the nutes I just feed them if I rewater with ph adjusted water.

And I have city water ( I live in the sticks but the water company said they get it from the city and adds more chlorine)

thanks

Knottyd

If you have proper drainage in your growpots, over watering should not be an issue, the excess will just run out the bottom. If you don't add some holes now.
If you decide to re-water, use nutes, as the old nutes will simply wash out the bottom.

Chlorine is less of a problem than people realize, it (excuse my spelling here) dissipates extremely fast when exposed to air. Almost instantly.
Peace

hey vid, im a bit unsure when it comes to ph'ing soil.
i always ph my water and nute sol to ph 6.5.
when i collect the run off its ph 6, so what is the ph off my soil?

the soil i use is bio bizz all mix and i dont add lime or anything else to it.

peace

The advice I got from Jangel was that the peat moss was dialing the PH down. As the peat decomposes I think it will continue to hold the PH down. I repotted getting rid of a lot of peat moss (the roots had not got into it too much, I was lucky). The new soil was a mix of bagged premium soil, perlite, dolomite lime, bone meal and zeolite. Now my runoff water is around 6.6 and my plants are happy. FYI, I'm using 3 part hydro nutes to feed them. When I mix the hydro nutes I always PH adjust them before I add them to the soil.

peace,
