Amirani Feminized Twins single seed

I decided to leave new born twins as they are. There is a big chance that their root system will create single uniform mass, since they are same strain, same genetics and germinated from the same seed, I will give it a try. I can remove 1 girl if she gets sick or something anytime. Lights are only MF1000 on 50% yet. Soil is Spanish Top Crop mix, which had good reviews. Growing in coco is easy, but for products in consume myself, I prefer it to be organic, so General Organics full line of nutrients is waiting to feed these twins :)
