If you're using a quality potting mix made for our type of plants, it should be fairly ph neutral...now if you're using soil that is made for fruit trees or something of those sorts, your soil may be acidic or otherwise inappropriate for MJ. You can purchase soil ph test kits from places like Lowes or Home Depot, or even soil PH meters. What soil are the plants in?
 
Hi Corenugzz,

Explain what you did with your soil. If it was branded which is it, someone may have experience using it. Also list any amendments you used.

Imo the soil needs some lime. Check the ph first, if it's too low add some lime. If the ph is a tad above 6 up to 7.5, i'd use gypsum.

The soil's likely a little too hot, the calcium will help condition the soil, and hopefully slow things down a little.
Depending on pot size, i'd probably start at around a tablespoons worth, and sprinkle it around the top soil. You can rake it in a little if you like, then water it in.

I think it'll help. Watch the lime if you need it, a little goes a long way, as far as ph goes. You can be rather liberal with gypsum though, it's good stuff, doesn't directly alter the ph. It's way more readily available than lime too.

Good luck, hope it helps.

Thanks so much for the info and I said the name of the soil I'm using is ace hardware organic soil

That soil has a lot of wood by products in it! Fresh wood chips too.....
Bet is does run high pH...

Looks like a poor soil to me......

Still
What do you feed and how much? List everything you add to your water....
What water?
What pH is the in-going solutions?

DO NOT buy a cheap soil meter! They are very unreliable...... Good soil, does not need to be pH metered!
Never meter the run off and expect any kind of accurate reading either - that is simply the pH of the run off, not the soil!

Just saying his soil looks a little over watered. The meter if not for the ph (at least he'll get an idea), for the wetness of his soil.

And you're right, good soil doesn't need to ph but I don't think we're dealing with good soil here.

I guess what I'm saying is, start with reducing moisture and check ph levels, then work on building better soil
 
If you want to test the pH of soil you need to do a slurry test. Testing the runoff does not give you the pH of the soil. And even then, you need to do multiple slurry tests with samples taken from different areas which really isn't feasible when growing in small pots. As long as you're not dumping highly acidic or highly alkaline solutions into your soil the pH will stay where it needs to be.

The entire "Check the runoff pH" when growing in soil is just something that newer growers are doing these days. It probably started with some dude on youtube and now a bunch of people are doing it despite the fact that it's not accurate. Checking pH is a hydro thing as soil is buffered to maintain pH where in hydro it's not. I see many people chasing their runoff pH in soil and then flushing their plants with massive amounts of pH'd water until the runoff is where they think it should be. They'll usually end up chasing problems their entire grow and end up with crappy plants that people compliment them on because they think that a finished plant should have crispy brown leaves at harvest because they saw some guy on youtube shilling his nonsense and that's how his plants looked.
 
Yeah, my pH pen was off and I was watering with over 7pH. It caused nutrient lockout but after realizing the error, it seems they are getting better.
 
Okay so I just saw ur guys posts. I'm out of town at the moment but will be able to have some pics for u guys Tuesday anyways 3 of the 4 plants recovered and 1 of them the leaves were weird and growing really funny and I decided to pull the odd one out

I think that's what happened here I used my pen to pH a faoliar spray with neem in it and I'm pretty such I was sent supposed to so I mad a stoner mistake but I tested pH with my dropper thing and it was a golden color with a lil green so like 6.5ish and I also added 2 cap fulls of ff soil nutrient formula and since then they have gotten better
