Noobiegrows Grapefruit Auto

Sept 23 - Day 58 - 37 F watered to runoff with ½ tsp cal-mag in 1/2 gal water. Broke my ph meter so just hoping it all works out. Sept 27 - Day 62 - 41 F watered to runoff ½ tsp cal-mag, ½ tsp tiger bloom, 3 tsp big bloom in 1/2 gal water. Ph 6.6 ppm 1220. I have been super busy so I haven't been able to document as much as I wanted too. She is getting fatter every week and leaves are yellowing bit by bit. Should have only a couple more weeks left before harvest but I will start checking the trichomes mid week 10. Only got one picture this week unfortunately. Will get more in week 10 for which has already started since I am documenting late!
