Does anyone know what going on here? They have been sprouted for 4 weeks

Medium, grow method, nutrients, feed schedule, water schedule, etc, etc, etc...?

Looks like the medium is no good for indoor growing .

Looks like the medium is no good for indoor growing .

The medium is fox farm ocean forest using fox farm grow big at a 1/4 teaspoon per gallon I’ve only gave them nutrients once so farm and I only water when the top 2 inches of soil drys out recently transplanted into the 1 gallon pots and added mykos when transplanting

Are you supplementing your water with CalMag? Looks a lot like a magnesium deficiency to me as it's on the lower older growth.

Someone with more expertise may jump in.....but this sure looks like a CalMag opportunity.

How are you adjusting the pH, and what are you adjusting it to?

I have not been suplimenting with cal mag I was wondering if that’s what it is I also use unfiltered well water to water plants

I have been adjusting it with ph down the ph is between 6.5 and 6.8

fox farm ocean forest lol so many people have problems on here using that crap its like every second person that got plant problems say their using fox farm ocean forest. im guessing its meant to be good soil but is clearly a bad product for a beginner grower

I've been using ffof as long as I've been a soil grower, about 3 years now and I've had only two plants that I can say were legitimately affected by a hot-spot, both seedlings, one survived, one didn't because I now recognize the signs and I flushed it

However that's not what you got going on, and in truth most cases where people blame ffof in reality it turns out to be grower error

Do you use a pH pen and if so did you calibrate it correctly, and do you calibrate it regularly?

..if it's a cheap yellow meter I would calibrate it every time I used it, I would also keep my pH at 6.5 in that particular medium going forward

I use a hm digital pen that I regularly calibrate I will adjust Water ph to 6.5 from now on thank you

I had one of those hm80 I think it was decent meter lasted about a year, still got it in a box somewhere I think it's right here

If you were in a hot spot in that soil you would have known it in the seedling stage because it's not going to affect a plant that age so you've got something else going on and I strongly suspect it's pH related

A Seedling on hot soil will just sit there and look progressively weirder until it eventually gets flushed or dies from what I've seen

You need to buy some of this and calibrate regularly at least get the 7.0 although dual point calibration is not a bad idea (I don't three point calibrate anymore I don't think it's necessary) because I suspect you're pH reading is not what you think it is

Next meter consider Apera meters, about the same price as the one you have and in my experience much better, plus it comes in a case with two bottles of calibration fluid and lots of instructions, but it's simple to calibrate (just press one button as it already recognizes when it's in the calibration solution) I have several and I've never seen one off by more than .1, and usually they don't go off at all, I calibrate like once a week if that, if I notice that it might be a little off otherwise I don't even think about it anymore.

In your case these are the two steps I would take (and I'm going to get killed for recommending flushing) but at least consider it. I don't recommend it often and I do it even less but I think in your case it would get you straightened out)

1) Buy 7.0 calibration solution and adjust meter. If you find it is off proceed to step number two below

2) flush those plants with 3x the volume of water that the container holds, Example: 1 gallon container = 3 gallons of pH 6.5 water (I've always felt this amount is a bit much water but that's what a flush is usually defined as)

Watch new growth it should straighten out for you you're going to lose the damaged leaves going forward but there's nothing you can do about that anyway

I just calibrated my pen the ph was off the water was at 7.1 should I flush with 6.5 water? S few other plants have small spots on the leave but the one in the picture has a lot

As I suspected! Yes follow step number 2 above and keep it at 6.5 steady going forward and your problem should go away, other than the lock out your currently having your plants look okay, good luck and call me back if I can help amigo!

Personally I would flush them all, because they're likely all having the same problem, depending how long they've been getting locked out, they're just not all showing it yet. I don't use 3x the volume (but honestly that's a topic for others to debate) but I would give them all a brand new start at the proper 6.5, if that were me.

Thanks for the help
