The beginning of this week i wanted to see if i could get away with 500 PPM and i learned i cant., so my water change i brought the PPM back up to 750. The PPM will rise with evaporation so remember to add fresh water threw out the week. but this caused the brown spots on the leafs, and now i know 750 is the max i should be feeding these plants and this will help tremendously next grow. other than that next week on day 60 i will start my flush for two weeks after that then harvest on day 74. Thanks for watching guys! watch the video for more information and happy growing!!
