How long has this been going on man? This couldn't have developed overnight.
I can't think of anything but pH lock out by the way those look. Just flushing with plain pH'd water isn't going to correct that. I would add hydrated lime and dolomite lime to a watering. However, you HAVE TO BE VERY CAREFUL, too much can kill your plants.
The MOST you can add of hydrated lime is about 0.5 cups per cubic foot of soil, and 2.5 cups of dolomite lime per cubic foot of soil. Hydrated lime works instantly and lasts about 2 weeks. The dolomitic lime is long acting and will stay in the soil to help buffer it. That should raise it about 1 point. Which should be enough. I really wouldn't go over that amount.
Good luck man.

The problem started about 1 1/2 weeks ago, and that's when I checked the run off and was like wtf. I'm goin out now to get some lime. How do you deal with the pH because I diligently make sure that the water going in is correct? Thanks hawk.

I don't know what's causing your soil to go so acidic. I never have to adjust the pH of my soil. Are you sure your meter is calibrated correctly?
I'm curious if there could be a possibility of a microbial imbalance that is causing it. That's really just a shot in the dark though. I always add Karma, and beneficial microbes to my plants.

Well, I'm back with some of this Pennington fast acting lime plus. Don't know if it's dolomite or hydrated, well it's not wet.
This is the stuff  It looks like this  It'actually a lot darker, the flash lightened it up good bit. I'm not quite sure how to go about applying this stuff.

I'm sure it's calibrated correctly and I also refer to my GH pH drops and they always match up.

Not the right stuff. You need dolomit, and hydrated. Hydrated lime isn't wet, it's just water soluble. And you want powdered dolomite lime. Pebbles are going going to take years to work.

Ok, thanks, that's all home depot had. Hopefully I'll be able to find something tomorrow. Is that why my hand feels tingly?

Thanks. I ran about 4 gal of pH balanced water through each bucket today(until you mentioned flushing isn't gonna help), when I hopefully get this stuff tomorrow, would you reccomend adding some nutes?

Once you get the pH corrected, yes I would. A small amount to begin with.

Are you saying I need dolomite AND hydrated? So I need to get them both?

Adding the dolomite lime to a watering will stabilize the PH and add calcium and lime to the soil. I think Epsom salt for plants (not the grocery store kind) will do the same thing.
What kind of water are you using though? The way that the young leaves have developed burned leaf tips plus the way they are yellow, smaller and slower to develop makes me think you have a chlorine toxicity in your soil. Severe chlorine deficiencies and excess of chlorine have the same yellowy bronze-colored leaf symptom though. It's pretty uncommon to have a deficiency of chlorine because most municipal water sources have chlorine found in them.
To treat a chlorine toxicity simply let your water sit out overnight, stirring occasionally, and the chlorine will volatilize and dissipate into the atmosphere. Use this water to mix your nutrient solution and feed your garden with. As you know, always know the PH of your water after the nutrient solution has been mixed into the water before you put the nutrient enriched water into the growing medium. Before water goes anywhere near my plants the water is dumped into a reservoir and left to sit for at least 24 hours to dechlorinate while a bubble stone runs in the water to oxygenate the water too.

I use my tap water and it has a ppm of about 120 and I ALWAYS let my jugs sit without a lid til I use it. Surely THAT wouldn't be my problem?

Do you stir the water? The water has to move in order for toxic levels of chlorine to be able to volatilize from the water. Adding a small electric water pump for the sole purpose of moving the water around works well for that application too.

I shake the shit out of it and my city's water Is supposedly a 4 ppm for chlorine.  I strongly believe its ph or what's affecting it.

Yes you want both. Hydrated will help fix it immediately. Dolomite will help in the long run. Remember to ere on the side of less is more.
It's wholly possible that something has changed in your tap water, or it's shitty tap water. Have obtained an analysis of it?
