Hey guys I have one plant in my closet, soil, cfls + led, 2 fans + dehumidifier,
temps: 70-85, rh: 60-65%, ph meter says soil is 7.0 (but i suspect it may be lying to me)
i feed with 15-30-15 food 1/3 strength every other watering
The plant has been flowering for around 5 weeks now
I know they have spider mites, but whats with all these brown spots?
the leaves eventually turn yellow and die, although some have brown spots and are still green.IMG_2475.jpgIMG_2476.jpg

Sorry mate those plants are in bad shape looks like mold and mite infestation. Keep them far away from any healthy plants and clean your grow area after you harvest or trash these ladies. I would get some neem oil and spray them it will help prevent mold and kill the spider mites.

*edit make sure you dont use neem too close to harvest it is natural but you really dont want to be smoking it.

fo sho, I actually do use neem, every week, a spray with water, neem, and tiny bit of soap, but these guys just keep coming back :(

I guess the picture's colors are pretty distorted, but the spots are brown, and they dont rub off or anything, I'm not sure its mold...

The brown spots are a necrosis on the leaves usually this is due to some type of stress or nute lockout (possible mag def). The mold is that white powder you see on the leaves.

The white stuff doesn't rub off either, I have some outdoor plants that have powdery mildew but this one I don't think has it.

I gave it dolomite lime about 2 weeks ago when I first noticed the brown spots, and some epsom salt last week, but nothing since then

Sorry, but it is very inconclusive; it is definitely not mold. I don't think it is cal or mag deficiency since I give them both. I have no idea what these spots are, do you know?

Or any advice at how to stop them from getting worse?
There's nothing mysterious about it. You've already been given several answers.

Yeah bro you have a bucket load of spidermites on there(white spots plus i can see them on top!). Get a miticide for plants asap treat it and repeat 5 days later, vacuum daily. If u leave it the harvest will be crap and smoke like garbage.
