First grow (gorilla cookies auto)

this week I noticed the soil was a bit warm so when I flushed I used cold water and that seemed to do good by the plant so not sure if there's science behind it but I like the results but not many changes really this week other than the mixture amounts, started adding more my goal is 6oz from this grow. i also started adding around 2 liters of water noticing the plant getting dry early and having to water a day early.
