Nutrients shortage (Quick one autoflowering x 6)

Use roots juice only , your soil is pre enriched and the plants can thrive for up to 3 weeks with no feeding so the roots juice will be an additive to the soil nutrients. If you are in coco , sorry it will be hard. Another tips is to use some homemade nitrogen with the bloom nuts to have a higher Nitrogen balance, for exemple you add 0,3 ec of nitrogen and 0,7 of bloom to have a 1ec feeding with more nitrogen .... now you will not like it but homemade nitrogen I am talking about is your piss , yes piss is full of nitrogen and don’t mix more than 1/3 piss for 2/3 water
