    New day new problems!

    Well thought I had my problems under control looks like not so much the case.

    All my old lower fan leaves are going completely yellow then dry out. On top of this my plants always look sad and droopy! No matter if it’s before a feed, after feeding all day same sad plants! Alsoy stems are terrifyingly purple, maybe due to the leds?

    Running Fluence 2i leds at 35% a few feet from canopy currently day 17 since I planted clones.

    Here is what I’ve been running environment

    Day time 80-82f
    Humidity - 72
    Night - 74f
    Humidity 66

    Vpd - 1 kpa


    They just got transplanted 2 days ago from 1gal to 5 gal royal gold coco/perlite.

    Any ideas what causing my lower growth to be so upset? New growth seems a lot better!

      I see some Leaf curl so to me it looks like you could back off the feedings for a few days and feed just straight water


      thats all I've got

        Thanks haven’t been water since transplant 2 days ago now, gave each one roughly 1.5 gallon , gave me a decent amount of run off.

        Isn’t it bad to feed straight water in coco?

        I had problems with nutes the first week so I’m hoping that’s what is still effecting the lower/older growth.

          If you’re using coco, use ph5.8 0.4EC cal mag instead of plain water. Idk what nutrient issues you had before but most of those leaves will never recover. I’d get rid of them. Focus on new growth. Check your run off ... if the numbers are out of whack you need to flush. Too many variables here. Easy answer: flush with .4ec calmag, then resume feeding ~.8-1.2EC.

              Have both the TrolMaster EC/PH probes in my res. I also check it against my blue lab pens. Both I have been calibrating every Week. PH has been around 5.8-6.1

              Will give flushing with just cal mag and remove all the dead growth a go tomorrow

                immobile issue at work here. starts from oldest growth. pluck cannibalized leaves move forward as usual.

                ph should be at 6.4 for coco unless its late bloom the drop to 6.0

                if running ro add calmag till 0.2EC

                note on calmag if it has iron it you're creating side issues with that

                    Coco coir should be:

                    6.0 throughout the grow
                    6.0 to 6.4 in heavy flowering (higher uptake of P/K)
                    5.5 after flowering (higher uptake of trace elements)

                    However mainly the grow should be 6.0. Coco coir does that automatically. Perlite buffers to a pH of 7.0.

                      Think you underwatering your plants, soil looks too dry,regardless how much nutrients you give them, even half the strength

                        I had just transplanted these two days ago into 5 gals wanted to let them dry out some in hopes of roots searching out more water. They will be getting water again tomorrow and will be on a everyday feed schedule after that

                          Underwatering helps rooting system think smarter, look for moisture?,In the meantime the only think they feed upon is nutrients included in soil, plus the extra(half strength) you've been giving them?

                            calmag plus is the issue here, too much iron at the ph you are running
