So all was okay, up untill 4 days ago. A real nice healthy green color.
I know my temps are on the high side.
85* to 89* RH is low around 30% or so.
Am using a blend of MG, Keith's organic soil, steer manure, EWCs, and perlite. 2 HydroCrunch 280w LED lamps.
4inch intake, 6inch exhaust, 31inch tower fan and one 6inch pole mounted fan. I started too notice some lighting of the healthy green I have had, and an ever so slight yellowing of the lowest most leaves. I watered yesterday for the first time in 3 days, and the soil was dry for it. I used bottled drinking water. Because I didn't want to ph down my well water last night. I noticed the yellowing was ever so slight before I watered. I had thought it was my nutes, from the previous watering 3 days before. Hence the bottled drinking water use. No nutes, straight water, no over feeding.
I raised my fixtures this evening, in case it was light burn.
What y'all think?

How close was your light to the plant previously? They look like they have been stunted of those are over 5 weeks old. I am guessing there is less than an inch between nodes....

5 1/2 weeks?? You got a ph problem that's stunting them.

So to be clear, I am running my water straight out of the well, and had PH'd the last feeding with the nutes down to 6.47, also at 1/4 strength on the nutes because its only the first feeding with nutes. And the nutes I am using is "Dutch Science Grow girls Grow. I am using 'General Hydroponics' PH Down to get there. Included here is the test result of the water sample I submitted to Pentaire before I got my new water softener. And to head off the question, before it's asked. I am not using the 'Softened water' to feed. it comes straight from the well. And with the water being high in Calcium and Magnesium. I don't think that is the issue. What say you?

When you say you are using a blend of those different things..."MG" meaning miracle grow right? Are you talking about miracle grow soil or miracle grow dry nutrients?

Do you know what your well water ph is?… mine is ~7.3. And I’m in soil also, which is my point. Your soil will, and can change how it buffers with your feed ph. I’ve seen mine crash into the upper 5’s , and had to do hard ph corrections…. Like up to 11.5 ph to correct it. Also, your well water should be fine… better than city water.

My well water is 7.37 PH.
I did include an summary of the sample I had tested on my well water.

Your light is way to weak. Below is a 5 week old plant from seed.

I know, my light is less than, what is available today when using LM301B diodes. But I do have 2 of these fixtures in my tent currently. I am pushing 480watts. And this is what I have till I can get a new fixture. My plants were doing just fine till 5 days ago. I really don't think it is the lamps, I could be wrong.

Okay, will a soil probe from the garden shop, work?

Honestly, no. I've tried a handful of PH tools, and the hard truth is, you get what you pay for. I ended up with an Apera 8500s... only because I grow commercial, and this is what I do for a living. $479, but it's been worth it for me. Saved a whole room once. I was chasing my tail trying to figure out why my crop was stunted and dying out. Got very low readings, and flushed 96 plants, re-fed, and everything bounced right back and finished fine.

Wow, truth be told. I can't afford 479.00 right now. That is a very expensive tool, especially for when I am only growing a few plants to get my feet wet here, to give my wife some medicine, because I am not going to buy this plant from a source where I could get into trouble with the law. I live in a state, where they very much do take you to jail for possession here.
I am just going to have to figure this out.
I know that when I watered with EWCs soaked/steeped for 24 hrs. I had no problems. I don't know what difference that made?
I will measure out the PH of the runoff, next time I water. Maybe that will give me some clue.

I can understand that... it's not for everybody. But we have to be absolutely sure. Yeah, try a slurry test of your runoff and use a ph strip, that might give you an idea of what's going on. Gotta do what you gotta do.

Yes, indeed. And I do appreciate your help here.

The only thing my 3-in-1 soil probe is good for is inaccurately measuring soil moisture and that’s about it! Like DoubleA said, a slurry test would do you some good. I have a sneaking suspicion your MG soil may have locked your plant out or was too hot.

Yeah.... I personally don’t add any additions to my soil during the veg phase and typically I can get 4-5 weeks before I have to add anything to my soil during flower. I use a pro mix, but soils already have all the nutrients you need. I would try establishing a simple baseline and then if needed add nutrients to your soil. If you overfed your plants you end up with a plant acting like it has “high cholesterol” with its veins being clogged.

however I have also seen plants stunt due to too intense light which is why I asked that first. For my lights I have them 4 feet above and only running at 50% for the first half of veg and then slowly increase my light intensity. However I’ve grown with CFLs, burple LEDs, and quantum boards. They all work to grow.

if you have more seeds I would pop a couple more and start over at this point. As someone else posted for 5 weeks you should have a plant over a foot tall at this point and even if you get it to recover it’s most likely never going to produce much weed. If you can afford another soil I would start there and literally just use soil water and light. Ignore the bottles nutes you purchased and pretend you don’t have them. They are mainly needed if you use a nutrientless substrate. The reason people transpot into bigger pots is that you are adding new soil for flower which has more nutrients which is why additional nutrients aren’t really needed at the beginning of flower either. Just some plants are heavy feeders and others are light feeders.

I personally start in a pint sized pot with starter soils that have very little nutrients. Then once I have a small bush about 6-8” I transplant into a 2 gallon pot. And then a couple weeks before I am about to flower I move into a 4 gallon pot.

So I got some PH testing solution. Which I had with my PH up & down kit. And some swimming pool PH test strips, ( this was all I could find local to me without waiting a week for delivery) I know its not ideal but its all I had. Plus I have my PH testing pen. So between these tools.
I ran a base test on the PH of a fresh gallon of Distilled water. Came out as expected, neutral.
Then ran 32ozs of this thru one pot. to find the runoff was nearly at or above 7. 5 or so. The pool test strips were completely useless at this point, so I had to go with the testing solution and my test pen results. And if I am to take these results as a "very basic" value of what is happening in the soil inside my pots. The soil is creating a PH value that is locking the soil up and chocking my plants. Correct?
And I do now have some proper Test strips coming from Amazon, since I can not find anything local to me here where I live.
