Purple Skunk Automatic Outdoor

It's my first time growing autos. Have the experience of growing a few couple of photoperiod plants. I also always planted outdoor and also never used nutrients. After sucessfull germination and sprounting of all the 3 seeds I've feed the plants with nuts from BioBizz Alg-a-Mic and Bio Grow. Two of them where planted on a 6L Airpot and one of 10L Airpot I had Root Juice that it was supposed to be used on these first weeks but I forgot it.
