Critical +2 auto & Moby Dick XXL auto

These seeds were given to me and later I mixed them, so I don’t know which one is Critical or Moby. They’re about 2,5 weeks into veg. I transplanted both of them, ‘cause I didn’t had pots when they sprouted. One of them is very small and don’t seem to grow (which is odd, since it was the first to sprout, in about 2 days. The bigger one sprouted in almost 7 days, both in wet cotton under the same conditions. I don’t overwater neither keep them dried. Whenever I touch the soil and feel like it’s drying, I water them a little bit, enough to leak a bit of water but not as much as a flush. Anyway, in the 1,5 week I put very very few Top Crop Bloom, like 1/4 of the dose per liter (as I read it was recommended to autoflowers), and in 2 week I put 1/4 of Top Crop Veg. They were closer to the light in the 1st week but I had to raise the LED ‘cause I have other plants in flower. Before, 1st week, about 30cm from light and now 60cm. Would appreciate some help and tips. I want to LST them but they seem too little to do it now.
