My weed plants getting eaten?brown spots

they are about 3 months old
outdoor grow
gets about 6-8 hours of light
i tried sopy water
overnight cigarettes juice
but nothing works
any help??
there my first 2 plants
both are different strains of reggie
i know i need bigger pots... but idk if thats the reason why it has brown spots
miracle grow is what im using
if you need more information ask please
oh and it used to have more leaves...
they slowly fall off. or i have to rip them off cuz of the damage...

the one with thiner leaves was a popcorn seed and the bud looks beautiful
about 3 weeks since it started to bud
wasent that good with keeping time track on it..

Looks like you are having magnesium deficiencies...yellowing spots turning brown + purple stems...you giving it any nutrients?

no the most i do is water it... lol 2 a day or 3 when the soil on top looks dry
are you sure? idk if you can see well, but with the fatter leaves. it has a slash across the leaf. like if they chewed on it. 2 leaves have the slash
and the thinner leaves have little chewing marks

One of mine did that near then end of it's life while I was growing it under lights and I tried everything to revive it but it seems that it's just a natrual part of that plants life it carried on growing after most of the leaves fell off. By the time I harvested it the stem was purple and only a few small leaves remained was easy to trim.

However you might have a completely different problem there. But 3 months and no nutrients I wouldn't be surprised if they're deficient in a few things.

hmm could be not enough light and its making them stressed but hey just random answer to the problem bro i do alot of outdoors and if this has just happened after 3 months of growth then i think it has something to do witht a massive change with the ammount of light were gettin through out the day i do think there stressed out and i always use micrale grow even b4 this stage o and just for the record i never give mine any power nutes till there about 5 months and iv never had problems with mine
