You’re fine😂 i know these things can be stressful, but let’er pull through, as tuankt said, could be fly poo, could be dirt, i wouldnt be concerned, the plant itself looks a very nice green

Check under the leaves, if there is spidermite they could be hiding there. If not, don't worry it maybe just dirt or dust 😬

Try taking a cloth dipped in some water and wiping it. That black spot could be caused by a fly or a leafhopper

At what stage do leaves get darker ? This is confusingI overwatered them at the beginning of veg and then I fed them with 0.7 ec nutes max, EC would go up if I gave more. I've had tips burning probably from light too close. I find that leaves are pretty dark but it may be because of the strains. When leaves do get darker in flo ?2 years ago
