Auto Daiquiri Lime/ First Time

Hi there! So its been week six. I will write the past week's details here also because its easier. Ok so the girl no.1 looks very very good. In the first weeks I thought the one day advantage was the answer for the size differences between the other two but you can clearly see now that it wasn't. She responded very well to the nutrient. The second one didn't responded very well and I and probably you can see as well (if the photo is not too bad). There are a few burnt, damaged leaves. Although I'm not quite sure if that's the reason but I stopped feeding her and seemed the burnt signs went away. And the third one.... In the first weeks I was hundred percent that this going to be the best phenotype even though it has a weird leaf from the beginning. So as you can see on the pictures (I Will upload some pictures tomorrow) burn signs everywhere. A new shoot is completely gone. I mean not completely but it looks horrible. But seems like the nutrient cut off helped her as well. So today lesson is be very very gentle when feeding this genotype. Despite the little errors I think they are doing very well and so am I even though this is my first grow.
