Brown spotting

This is my first grow and don’t know too much but I’ve got 4, 31/2 week old white widow’s and I’ve noticed one has gotten some brown spotting and some bumps on the stem. The rest are completely fine just this one is experiencing this. Any help on how to fix and prevent this will be dope. I’ve researched it and came up with alternaria but I want make sure what it is

They're awfully small for 3.5 weeks. That's all I got with the info provided.
Please give us all the details you can.

Looks like she was fried from nute burn.

Can you provide some more info, what type of soil are you using, lights, nutes, etc? As person above said those look very small for 3.5 weeks. Around 3 weeks from seeds is when plants usually start exploding with growth. From the looks of your pic I would say heat stress and or nute burn.

Did you do any basic research at all before starting?
The rest are pretty far from fine. Might as well just start over, man....

Yep. You can always feed straight water for a while to see if they get better but the new growth looks pretty crappy too so it's probably better to just restart from zero.

Transplant them into new LARGER containers with fresh medium .... bury those over stretched stems ( it will aid in rooting ). You might be rootbound.

What is your light height ? Bring that shit down to 18”. Temper excess stretch.

If running good bagged soil mix , just water ( a little when you transplant ) to temper shock and just enough for roots to begin to SEEK more. Let the medium do the feeding .... dont over power them. They will come around at their own pace as long as you dont hover over them and goof up on something.

Yea I'd say definitely nutrient burn and probably overwated too (possibly with wrong ph) with the little info provided. Definitely need to transplant too a bigger pot. If in soil dont give any added nutrients, just ph tap water to 6.8 and only water when pot feels light to pick up. My advice first is to do some extensive research about growing whatever way you plan too, in soil, indoors and with 'x' kind of lighting. I probably spent over 500hrs reading and researching before I started my first grow and it was decent for a first, but I still ran into a few problems and learned alot. So even if you completely screw the pooch on your first 10 grows, it's never for naught, you always learn something and come out more experienced for the next. Second, to get the best advice here or any forum, you need to provide more information. Medium (soil, coco, hydro ect) if in soil what brand (Fox farm, Aurora ect) if adding nutes what and how much, type of lighting used and how far from plants, temperature and humidity of grow area, and water schedule and ph. I wouldnt give up on em I'd stick with it for the experience, you'll get some buds just keep your expectations low, something's better than nothing! Good luck man

:::: forgot what forum I posted this on. I’m using 1000w power bloom at about 20in away I’ve since transplanted them into 3 gal pots using fox farm ocean Forrest soil and mycorrhizal fungi and watered with 6.5 ph molasses M,W,F. temp indoor stays @70F + - 5 degrees. Idk humidity honestly. One picture is a week after my transplant and today

The one in the small pot was the bad one and I gave up on it but I’m gonna transplant it and give it to my buddy who’s gonna try and save it

Nice man! They're looking much better, I'd definitely try and do some Low stress training with em if you can, it might be a little late for the ones on the ends to get a completely even canopy but you can get close, otherwise you'll have one main coal at the top and a bunch of immature buds under it
