Base leaves gettin yellow

i have around twenty plants. i have about three in one big pot. most of my pplants are doing well so far, but for the three in this one pot, the base leaves are turning yellow and dying. this started about a week and a half ago. the leaves that are still green towards the top are really droopy. i know im not overwatering bc all the plants are wattered together, so these are receiving as much/or as little water as the others. these plants are also not as tall as the others either. by the way all the plants are about a month old. about two weeks ago they were all looking the exact same. if ne 1 knows what might be causing the fast and sudden death of my babes, please tell me.
i will try to get pics of all the plants soon. i have a camera but dont know how to get the pics on the thread. if ne one knows about this either, please tell me how to do it.

You cannot grow suitable plants in combination in the same pot container without problems. They compete for everything and eventually they all lose.

Cut the two shortest plants and say goodbye to them and focus on saving the best.

Cut them about 2" below the soil surface.

You have no other choice other than transplant and at one month old, you'll likely lose all three.

Cut the two weakest and the third will be ok.

damn! that sucks. im not disputing the facts that you said, but i do have about six plants in one pot. they are all about a foot and 4 inches so far. they are looking great. im wondering of theyll all fuck up like these three? hopefully not. ill try to get these pics up as soon as someone can tell me how.

Ussually about half way into flowering. All will die exept one. Sometime they all die.
Transplant them to seperate pots now. iIf the roots are tangled. Just take a butter knife and cut them .
Replant and feed with a root stimulator.

Believe what you wish.
