Soil PH too high, need advice

[Zooter]

Hi everyone, hope I can get a little advice on this. I tested the soil tonight cause I’ve been having yellowing problems with all my ladies. The result was 7 or a little more depending on which plant. That would explain the issues I’ve seen.
The question is, what is the best and hopefully quickest why to fit this problem before I loose the crop. All the plants are still in veg stage.
Thanks in advance, appreciate the help !👍

7 is not that bad for soil it's the very top of the recommend 6 - 7 it needs to go down but it's not a panic issue. A couple pictures would help for helping with a diagnosis. I would also need to know what you are feeding because this will change the answer as well on bringing down the ph

Thanks for your reply. I attached a couple of pics. I’m thinking the nutes have been at least partially blocked by the problem. Using all Fox Farm products. Hardly done much feeding as they were transplanted up last week. Nutes at 50% strength.
Thanks again

The first picture she looks a little hungry but the other ones look happy. To bring the ph down I would on your next watering ph it like 6.2 and make sure you get 10-20% runoff. Runoff is important to wash out any uneaten foods from before so if you don't get enough runoff the foods will build up in the soil causing issues with your ph

MeEasy is correct. Reduce your PH by using PH down in your water. Set it to about 6.5. Add some Cal Mag.

Thanks everyone ! Will do 👍

PH down=acid, some use vinegar, lemons, black strap molasses, I use sulfuric acid for immediate PH down and pelleted sulfur for buffering.

Update. The plants were watered with average 6.0 to 6.25 PH. The run off measured a lower PH, around 5.6-5.9 I’m totally confused at this point. I thought it would come out above 6 or more. The soil ph tester might be wrong in the first place. I stuck in the yard and had the same reading as in the Fox Farm. I think it’s not working.
Any advice going forward ?
Thanks

Those soil pH testers aren't the best. Never heard of one working.

If the plants seem to be struggling aside from PH you need to ensure all the other aspects of the grow have been checked. Light, Heat, Humidity, Nutrients, watering practices all factor in with correcting the PH.

To be honest I rarely check the soil PH because I Flush at least once per grow. Never had a problem, plants produce decent buds...

Having said all this, I have been reading about liquid seaweed (kelp) fertilizer like "BUD Juice - Base" as a soil enhancer. Apparently it works great at conditioning the PH in soil, amongst other good things.
