To me it looks like damage caused by the leaf hitting the edge of the pot when it is windy, maybe the same thing with the other leaf but hitting the ground maybe. especially when the leaves are young and tender, they are more easily damaged. Not all of your leaves will be perfect, nature has many random things that will do some strange things once in a while and to expect 100% perfect leaves 100% of the time is just not going to happen. It is a bit like a child falling off of a bicycle, we all suffer the odd injury every now and then and those little injuries on your plant are nothing to be worried about, your plant will still continue to grow as though nothing had happened. Also, a tip for your next grow, fill your pots up right to the top, this will provide much more room for your plants roots to grow and you will get bigger plants too. Finally, I would suggest giving more than 200ml every 2-3 days, this is barely enough and when you consider that even at this size, your plants roots would no doubt be at the bottom of the pot already, and 200ml is not going to be enough to get the entire pot moist. I would suggest at least 1 litre every 2-3 days depending on temperatures, and you want to be seeing water coming out of the bottom of the pot to know the water has penetrated the entire depth of your substrate. Once your plants are older and start flowering, they may even need as much as 2-3 litres a day if it is hot! Hope this helps,... Organoman.

As you described, your cuttings may be rotting. But without pictures it's hard to say. Did your lid have holes to let your clones breath ?
