First Grow! Ethos, Purple City, Mephisto

To be honest, it's not the size of the pots that is going to be the problem... nor IS it a problem! The pots are always going to stay the same size.. it's the plants that will grow. You're going to have a space problem anyway, trying to fit 3 autos in that size tent but there you are... smaller pots will NOT equal smaller plants unless you go to something like a solo cup! LOL! And autoflowers absolutely hate being transplanted so please don't do that. What I would suggest you do is plan to do some serious LST (and you can LST as often and as much as you need to) ... and you'll probably have to do some defoliation as well... which will probably include choosing only the best bud sites to leave and trimming off a LOT of lower bud sites. Good luck! You're going to have a jungle! Make sure, when they get into flower, that you keep the humidity low (30s-40s) so you don't run into fungus/bud rot issues...

That is such a hard decision... I know I've told you to prepare for a jungle - and you should - this is going to have to be your decision - but why don't you wait until they're bigger and you can see what they become? Look at it this way... let's say you pitch one plant today but in 4 weeks time, you realize you COULD have fit that 3rd one in and been ok... or in 4 weeks time, one plant dies of its own accord because of X, Y or Z and now you're left with only 1 plant... Stick it out until you can't stick it out any longer... You can do this! You really can!!!

Hi! Your plants look just fine. This is OG Kush genetics. I’ve had the same with mine from the same stage.

Probably just some nutes that dripped on the leaf... have you tried to wipe it off with a damp cloth? It certainly doesn't look like a nute issue nor does it look like WPM... I wouldn't worry about it myself... good luck!

I'd keep my eye on them, tbh... it certainly COULD be from the heater but it might also be the beginnings of a phosphorus deficiency.... I don't see any pH information or nute information in your diary - but you need to keep the pH between 6.0 and 6.5 for a soil grow... Good luck! Nice looking jungle so far! :-D Did you decide to keep all of them going? Hope so!
