First off we need a certain amaount of information anytime you need a diagnosis.
What soil are you using, how big of pot?
What is you water ph?
what nutes do you use?
How old is she?
What lights?
ok so here we go. As i access your problem I really wish you had more and better pics. Im working with what I got and I wanna help but next time, take more photos for us? The curling under can be a couple things. Under or over watering will do this. Now I kno that snot what you wanna hear but you have to learn how to tell which is which. If you recently watered before you took pic, you have over watered. How long were they drooping? The red spots could be bugs and thats not good. Also Im think a possible mg deficiency, but wont know that until I get more pics of the spots and info on your grow. You dont use tap water do you? Our tap water down here is GARBAGE. Literally
