High bro, I am new to diagnosing plant problems, but I think that looks like problems with the PH? It reminds me of the photos on https://www.growweedeasy.com/ph-fluctuations-cannabis Are you checking the PH before you water? Also that soil looks very rocky, I don't know if that matter it is just an observation. Hopefully somebody good at this can help you out. Also, depending your native language you might have more luck in an international forum. https://www.icmag.com/ic/forumdisplay.php?f=27 Good luck bro!

deficiencia de algo...potasio o algun macroelemto,tambien puede ser el tipo de sustrato que utilizas

I agree w the pH diagnosis.
That should always be the first thing you check as well.

Ditto on the ph idea that spotting is a telltale sign the plant under that nifty humidity dome looks better though. Maybe there's some watering issues here contributing to the ph problem. How often are you watering them and how much? Also what kind of soil/nutes are you using?

I wouldn't, myself, get too excited over a few spots of necrosis unless it's gallopingly progressive...

Poor air circulation, possibly!

Keep it alive.
Once gets a little larger, put in a bigger container with nice soil.

The soil looks shit...

...i agree the soil looks like crap and appears to need some perlite to improve drainage.

...i'd also agree that ph might be part of your problem but i'm thinking that the cause might be from too much media in the pot for a plant so small.

...i'd also suggest that you lose the 'dome', at this point it should be unnecessary.

peace, bozo

Looks like dirt dug out of somebody's yard or something spring for some quality potting soil man your plants will thank you for it.
