Hi everyone. This is an auto, she's 33 days old. To me she looks nice and looks healthy but I'm new to growing, so just wondering if anyone can notice anything wrong going on?

Actually just noticed a problem when I was looking up at the plant. I could see dots on some of the leaves. They look like tiny rust dots. They look different on the picture

Pests? Look under the leaves with your microscope.

Doesn't seen to be anything moving but was cool looking at them under a microscope. After some research I believe it may be lack of magnesium, I haven't given them any nutes yet so I believe that may be the cause. Thanks for your reply.

Before you douse them with nutrients I would inspect more for pests. Also they look a little heat stressed, but the plants themselves look like they were under lit. Did you add a new light halfway through?

Still pretty moist from last watering so was going to feed them tomorrow or the next day. In the meantime I will look for pests again. I do have another plant right beside it which seems totally unaffected.
On the heat stress I would say it has been warm here recently, would you suggest I add another fan? The one I have is only a tiny thing. Also I have the fan on the same timer as the light, which is on 20 hours. Should the fan be run constantly?
I didn't add an extra light or anything like that, it's under a 100w led bulb. I know it could do with more but I was just seeing how I'd go with my first grow and if I managed to keep it alive I'll invest in more wattage.

Well the heat stress is usually from the light, but 100w shouldn't be strong enough. So I'm not sure what's going on. It's not good to continuously blast a plant with a fan, but having continuous air movement is a good thing. So an oscillating fan would be good.

You need a better light first and foremost.

Would it be to close to the light maybe that would cause the heat stress? However it's not red from too much light.
The fan I use is pointing at the wall and bouncing the air around instead of pointing it at the plant. I do have an oscillating fan for myself so maybe I'll stick that with the plants instead.
Edited: could heat stress be mistaken for underwatering?

Looking at them again, I think it was just the contrast of the background. They don't look too stressed at all. I think you're fine.
 
They really do need more light though. 100w of LED is hardly anything. They will stretch instead of bulking out during veg, and you're just going to grow larf in flower.
 
Also the tips of some of the leaves are pointing down, which usually means too much nitrogen. I'm not sure of your medium and/or nutrients, but better lighting would help that as well.

I don't want to scare you. All in all the plants don't look too bad. Just craving more sun and possibly a more balanced, more suitable EC.
