My first Grow

Sooo after a little setback i am back in the game i think. Sadly i overwatered my Runtz a little bit and had to change the soil because it was veeeery wet and also leafs changed to a certain unhealthy color....also i will change my fertilizer in the future because i hate the hassle with the liquid fertilizers....i will start mixing my own slow feeding fertilizer and will add a NPK mixture of 4-4-4 and also some Mycorrhiza. My GSC looks healthy and is very easy going at the moment. Also i received my new little growtent from Homebox and added also a new lamp from AC Infinity. At the moment i am running the light on 430 ppfd (at least my phone says so...) With the VPD i am trying to be in a range of 0.60-0.80
