    My plant seems to be evincing a number of symptoms of what could be a nutrient deficiency or nute burn?

    Info:
    grow set up: hydro waterfarm
    strain: white widow
    age: 2 months and 20 days old
    Veg time: 9 weeks (Cycle: 20/4)
    flowering: it's currently 2 weeks and 3 days into flowering
    nute cycle: I am using the fox farm nutes and solubles, currently at "week 7" in fox farms nute schedule

    Anyone have any ideas of what might be causing the yellowing, the drying tips, ect

    thank you for indulging my ignorance,
    &
    thank you in advance for your help

    I like to keep Ph for soil around 6.5-7.0. For hydro should be @ 5.8. You have a tds meter? You should flush and reduce the amount. The reccomended dosage is already too much. You should feed a less then what they reccomend.
     
  11. I flushed this morning after relieving the reservoir of half its water. And no, I do have a tds meter. Which tds meter would you recommend?
     
  12. I have a 2 in 1 ph/tds meter pen by hanna. I bought it for 200$ a few years ago. Works great.
     
  13. Despite 4 flushes and two smaller nutrient doses, My plant is still quite sickly. The water ph is 5.7-5.8. It's gone limp, drooping and slowly shriveling. It seems like it's slowly dying. though, there doesn't seem to be any problems[​IMG]
     
  14. Is it possible the waterfarm's too small for the plant....?
     
  15. i wouldn't use all that stuff that foxfarm says to use.. especially in those amounts and with that frequency.
