Cuckoo - Unknown Thai Strain

I was given a bunch of seeds by someone who has no interest in the genetics beyond the smoke. I attempted to germinate about 20 seeds. This was the 1st seed to germinate however once the other 6 seeds had germinated it became clear that the appearance of this seedling is remarkably different to that of the others - see the Monty Diary I think I have been over watering so I have knocked that back. I'll see how that goes over the next week. Just received delivery of nutrients from Siam Sativa, so I will begin that regime and see how that goes over the next week. A plant app that I was trying out suggested an area with more light so I have relocated all the plants and see how that goes over the next week. Soil metre on the way so hopefully that will remove some of the guesswork. Can't help but get the feeling I'm making a lot of mistakes
