Well... I lifted the pots and they were still heavy. I don't want to waterlog them, so we did not give any nutrients. Hopefully, they'll be okay for a couple more days.

Good choice Grandpa, make the roots seek the water, water only on the outside of the pots, I have been comparing this grow to your last and the problems you have had in the past couple weeks are a lot like the first grow, maybe too much light or too close may be a partial factor, but I think over watering along with adding too much goodies is a major factor...remember your soil mix should have all the basics for your plants for the entire grow, adding more will basically create a lock-out if they are not getting a balance of water and nutes.
I would recommend only a taste of just PH'd water...not to run-off just to wet the soil when the pots feel light for a week or so and only around the outside edge of the pot.
If your tent temps are between 75 at the lower part and 85 at the top with a slight breeze circulating over the plants you should be good, if its hot at the base of the plants, the soil will absorb the temps and act like a oven trying to cook the roots so keep that in mind.
Another thing to consider is plants like a 50% humidity range when growing, a towel hanging out of a dish of water will bring the humidity up if its low...natural evaporation.

OT...great to hear from you again! Hope and pray everything is going well for you and yours. I see the points you are making and they are more than valid. I'm almost 100% sure that the temps have been fine as the room air in the room around the tent very seldom raises above / 75 to 76 degrees, so even if the lights were causing more heat, it should be well within that range. The humidity, on the other hand, maybe an issue as we have not been measuring that, assuming that it would be okay, because of the humidifier that is in the room for Kelley's lungs. I guess we should start reading the humidity in the tent proper. Before we did the flushing, the pots were very like. And we have been waiting in between waterings to let the girls show us when they need it. When I checked yesterday, they were still heavy from that Flushing. It was my understanding that the soil alone had enough nutrients for five to six weeks of growth. When we first started seeing the yellowing of the leaves, we decided to give them a light concentration of nutes, even though it was a little early for them. Even though we didn't use it the first grow, PW has reported that the Mammoth P is causing issues with other Growers. I'm thinking that possibly even the small amount we have used on this grow may have something to do with it as well. They do seem happier since we turned the one light off two or three days after the Flushing, though.
Thank you for all that wonderful input. The more details the better as I learn best from being told how, then doing it and being corrected as I do it. That's why I need a lot of detail at times. Don't be a stranger, man! This thread is nothing than more positive with you around. God bless!

Sorry I haven't been posting much lately Grandpa, been busy around here with my current harvest, clones, and trying to bring some old 70's Maui Wowie seed back to life!
I have never used the Mammoth P so can't advise you on that, what are your PPM's that come out of your tap? Mine are in the 350 range here so to make it easier for me to know how much I am actually feeding them I use RO water, add the nutes at the rates given for the stage they are at and then adjust the PH up or down.
When I was vegging, I was always adjusting the PH down, when I switched to flower, I had to adjust the PH up...mine were photos, but I don't think that makes much of a difference, they still require different goodies at the different stages.
I think it would be a good idea to see what you have for humidity in your tent, take a readings with the tent closed at lights off and lights on for the whole cycle as they are now...in my room the RH was around 50% with lights on and would rise up to 60-65% with lights off.
A gentle breeze aimed at the plants will help dry your soil and also keep the plants from "sweating" if you do have too much humidity, but my guess is it may be too dry in your tent and the addition of that second light made it worse.
I am always in the background rooting for you both! and if you get bored, swing by my journal and see a crazy old man in action!

Great info OldTimingman, great info! You know that's all I heard at first from Grow stores is here you need this Mammouth P. Through out. Well I really think that it was a problem on my one plant that I used it on. On my other plant no real issues and I have not used any of it. The one I am using it on seems like I have to watch it more carefully as the tips of the leaves started to burn.
So I just quit using it and in a week no more new burns. So that really makes me wonder. I thought it was just me but I have noticed people here on 420 have been talking about it. So I see no need to use it. There is better stuff out there so I'd be careful using MammouthP.
:Happy Growing:

OT...not sure about the PPMs. Mainly because I just don't know what that reading indicates or how to actually adjust and when to adjust. Simply put, I haven't done any research on that yet. We will definitely check the Rh over 24 hours and see where we are. As far as the water, we are using water that has been bubbling or at least 24 hours, then then, then applying. If we did use nutes, be red and then adjusted pH after they were added to the water. We are consistently having to drop the pH from between 7.5 and 8 down to between 6.3 and 6.5.
I am also thinking that we may need to add a second fan, and use it as an intake fans to complement the exhaust fan on the other side of the tent. The clip on fan is now aim to give them the gentle breeze you mention. Good luck with those Maui Wowee seeds. I sure wish that I had kept a few of the ones that we habitually threw away back in the late sixties and seventies. Could you please put the link to your Journal all by itself in either a post here or in a p.m. to me please?
BB...I have heard and read the same things around here about Mammoth. Received we received what we have as a freebie when we bought our Earth Juice. We will no longer be using it in the regular regimen that any longer. I will also recommend against it to anyone with questions about it.

Quick report...
Kelley tells me that Emma is showing a lot of new growth, most all green and some with a little brown on the tips. Just the fact that she is throwing New Growth is encouraging. Elsa, on the other hand, seems to be stuck where she is. She is also showing a little bit of limpness in the leaves. Soon as is possible, I will post it the pics of them as they are now. Not sure what to do with Elsa...

Okay here are the pics. Apparently Emma is really branching out. Maybe that accidental crimping caused her to do exactly what she is supposed to. Apparently she's trying to push out. Apparently also some of her newer leaves are beginning to turn. Some are still green others have started to Brown. Elsa just seems stuck where she is. Apparently there is no further growth to be observed. I'll let you guys be the judges...

Sorry , but are you adding cal mag under them led lights bud?
Also maybe get few others thoughts but maybe remove some of those lower Dead leaves that won't be receiving a lot of light anyways ? Thinking out loud here

King...welcome and thank you in advance for your help! No, I am not adding any Cal/Mag to them. I have seen a few differing articles on whether to use that with Autos. I do know that when you use LEDs that Cal Mag can become deficient. There are arguments saying that the lifespan of an auto doesn't make a difference, and others that say you will need it with Autos as well as photos. So... I guess I now have to learn from experience. What would be the best other than the chemical supplements to use for that need?

Eyes4Grandpa, just a quick thought.. are you using tap or well water? If it's tap, I'd like to take a look at your municipal water report. From everything I've read, your environment, nutrients, soil are beyond sufficient to grow healthy vibrant plants. I just have this idea in my head that due to you having to constantly adjust PH from 7.5 or 8, down, that the issue may be originating from the water source. I want to see you succeed and have amazing meds, my heart is with you!
Damn I know there are more organic alternatives the. Harder chemicals such as Cal mag but I was told form a very amazing individual on here that adding small amounts under led lights is cheap insurance . However your in soil so I dot. Have a lot of experience with soil unfortunately.
Crap umm here is some thoughts from
Web ?
For different alternatives .
However never use miracle grow soil please .....
And here is a chart for how to diagnose def probs?
Always start checking run off ppm and ph first make sure your in range .
I'm here to help Grandpa, you may pick my brain but sometimes it's under construction. 
In the meantime, I'll read through your journal to get caught up in hopes to join you for the long haul.
I humbly offer support and stories that you may find useful or funny.
Respectfully, so far I'm predicting cal/mag deficiency, nute burn and light burn?
I'll be back to confirm or deny those predictions for fun.
Thanks for putting out those chairs, it's getting comfy in here now.

Joe, based on this chart, his plant appears to be suffering symptoms similar to K, and CI.. His nutrient lineup has traces of Magnesium and Calcium, by all means he shouldn't be experiencing deficiencies. Excess is entirely possible, but I'm leaning more towards sediment lockout. I also live in an area where water from my tap runs roughly 7.8 at a little less than 500ppm.. before I got my PPM and PH meter, my plants exhibited very similar necrosis in the leaves. At first it looked like Iron def, then before I knew it the leaves curled up and diedDamn I know there are more organic alternatives the.

I wanna know what exactly is in his water before recommending he add more of anything.

Good call this is why second opinions I always recommend.
The only thing that makes me think cal mag is the leafs are yellow on tips and browning ?
Also I agree I looked over chart and agree with the other symptoms you said
CI and K ?
Let's figure this out for him...
Would it be possible to see close up pictures of some of the affected leaves? From here I am not sure if it looks more like nutrient burn or a potassium deficiency.

We're definitely gonna try to figure it out. I'm scanning through his last grow and it's definitely making me more and more confident that what we're seeing in his plants is a blockage of sorts
I'm almost entirely sure it isn't a deficiency. There's no way it could be a deficiency. Something is blocking nutrient uptake at the root level

What about his ph testing?

I believe I read that he's constantly adjusting PH to 6.3-6.8 because his water is 7.5+
