    HELP ! Fist time grower, Hydro, yellow leaves

    HI!
    First time grower here, also English is not my first language so sorry if my explanations are not clear.
    Like you can see in the pictures I’m having a yellowing leaves problem, I’m almost week 3 into flowering and I would say the problem started right after the switch to 12/12 (I defoliated at that time), but I always had a little bit of yellow in my leaves.
    From what I see, parts of the plant that are affected are all of the new leaves, not necessarily those at the top of the plant.
    My setup:
    • Hydroponic, using 5 gal buckets
    • Light is an 8 x t5 bulbs fixture (430w)
    • I’m using general hydroponic flora series and following this chart:
    https://www.growweedeasy.com/wp-cont...t-schedule.pdf
    • I’m using tap water (come out of the kitchen tap at 300ppm) and I’m at about 800-900 ppm once I added the nutrients
    • I add clean water and adjust the PH (between 5.5 and 6) everyday or every two days. When I adjust the PH, its never over 6.3.
    What is going on !?

    If I am not mistaken, I think your ph is too low...

    i could be wrong, wait for a dwc guy/gal.

    Please visit www.honestgr.ca for reviews on grow equipment. It is going slowly as I am trying to find products to review (and supportive companies!) I do giveaways there, do not tell me your from GWE however.

    I'm going to take a wack at it and say they're going through some Potassium deficiency.

      looks to me as if it's a potassium deficiency. I'd up your ppms a bit. to 1100 or so at least if you can as potassium can be absorbed pretty well at a wide range of pH so shouldn't be a pH problem.
      you start with 300ppm and are only going up another 600ppm.
      I don't grow hydro but I grow in coir. In flower my plants get about 1150ppm when my tap water comes out less than 100

          Take ozbuds advice. If you tap is 300 get you final up to 1300ish so that your nutes are 1000 and 1100
