looks like they just need to be fed to me. maybe a little extra cal mag wouldn't hurt, but don't over do it

Probably add less water and nutrients if under the LED grow light.

Can someone help me figure out what’s wrong with my plants? They are all doing the samething some worse than others.
Basically a lot of the bottom leaves have turned yellow and died or are turning yellow.
I am day 12 of flower also I added some nitrogen because i thought that would help but has not,, and tried calcium... No idea what it is at this point. I’m using go box general organics. Overall they all seem to be doing pretty well but their bottom leaves are turning yellow.
Also My normal water is 6.5 pH, I’ve been pHing up to 6.0 with nutes, Run off is 6.1-6.5

what are you growing in? soil, coco, peat?
ph soil to 6.5, coco to 6.3, and peat to 6.1.....doesn't sound like a big difference, but trust me, it's more than enough to cause lockouts over time. don't worry about run off ph in soil or soil-less medium. as long as you're putting it in in the right range, it'll be fine.
when you put a plant into flower you have to feed it a little more. not a shit ton, but it's producing a lot of new growth, and it'll eat itself to do it if you don't feed it enough. i use jack's at 3-4-3 during veg, and add some calcium nitrate every other time. in flower i use jack's tomato feed, it's 12-15-30 with added calcium. they seem to like it a lot, and i like the ratio.

I am in happy frog/OF Foxfarm mix.
I’ve been adding nutes for flower so I brought the pH up to you 6.0 after adding nutes.
I think it’s potentially a calcium or mag problem because I just recently started supplementing with Cal mag (I’m in well water so didn’t think I would need it )
They actually look great to me but at the same time they have a ton of bottom yellow leaves. I think it probably is a pH problem
unfortunately I just broke my pH and I’m waiting for a new one in the mail

It’s looking pretty bad today. When I water them they come to life after a couple hours but then before they get completely dry they start to droop. I also wondered if it could be a root bound problem but I don’t think that’s what it is. I think it’s either PH or calcium thing

Get a TDS meter. My first few grows, all I used was a pH meter, after upgrading I got a professional meter that reads TDS, EC and pH. This thing completely changed how I feed my plants. (I grow in soil or soil/coco mix). It’s difficult to diagnose your plants without knowing if they are properly taking up the nutes and a TDS meter will solve all your problems.

Should I spray the epson salt on the leaves for put it on top of the soil?

If in veg u can spray leaves
I’m not sure that you should in flpeer but I was wondering the same thing
Make sure you only do it right before the lights go off

You can also just mix 1 teaspoon per gallon of water Epsom salt and water your plants with it

When a cannabis plant or seedling has a purple stem without any other signs of problems, it is often the result of genetics. However, sometimes you'll see red stems (pictured right) which can sometimes be caused by stress, environment or pH problems.
Wait a week or two before making any alterations if your plant otherwise appears healthy and is growing fast.
If there are no other symptoms and the rest of the plant is growing fast and healthy, red stems usually aren't a big deal. Often stems turn green on their own. As long as you're continuing to take good care of your plant and responding quickly to any other problems, you should be okay.
These red stems were caused by transplant shock and overall stress, but the clone just needed some TLC and time to grow out of it.
I HAVE A PIC BUT I STILL CAN'T UPLOAD A PIC … DON'T FIGURE

. You’re growing hydro with flora trio, and you’re getting a 6.0-6.5pH of your feeding water? What does your water test without the flora trio?

One thing is light. Are your plants getting enough light. Another is what kind of water are you using. Flora Trio makes it very easy but you have to follow their specific notes on when/how.

I believe what you have is a phosphorus deficiency. When plants lack phosphorus, purpling or reddening of the leaves and stems can occur. Signs usually begin in lower leaves and branches and slowly work their way up the plant.
Bear in mind that some plants naturally turn red or purple due to their genetics but if you keep having this problem with many different strains, it’s probably not due to genes. Overwatering and cold temperatures can also exacerbate the problem so make sure those aren’t an issue for you before trying to add more nutes.
Phosphorus is the “P” in NPK (Nitrogen, Phosphorus, Potassium) meaning it’s a major nutrient needed by the plant to thrive. Most fertilizers made for the flowering stage will contain plenty of P and sometimes growers will mistake a pH imbalance for a deficiency, although it sounds like you check pH often so in your case I think it’s truly a lack of Phosphorus.
In order to treat this deficiency, you need to add nutrients with phosphorus. Organic forms of these include worm castings, bat guano, bone and blood meal and crab shells among others. If using bottled solution, use something where the NPK shows high levels of P. Most flowering or blooming nutrients meant for cannabis contain plenty of P. You should see the problem clear up within a week or so with new growth looking lush and green.

looks like a little too much N, and probably a ph problem....looks a little like mag deficiency, but i don't think it is....i think your ph is a little off....
