    Limp and yellow plants

    Hi, I've done about 4 grows and haven't been very successful. My setup:

    Viparspectra 450w leds

    Grocell 1.8m tent

    Fan and exhaust fan on timer

    I monitor heat and humidity and it never gets above 23c/73f, I have thermostat heater as it's winter here.

    I don't think I'm overwatering either. Have had lots of bugs but that has cleared up somewhat

    My plants seem to start well but periodically become very limp and yellow. I've tried boosting with nutrients, ive raised my lights to a distance of 80cm / 32 inch (basically as high as possible)

    They are always small plants as well. Big one us about 50cm

    The pics are in flowering stage

    Please help if you can - I think it's light intensity, but have tried other leds that have a dimmer so could experiment with intensity, but couldn't make it work

    Any help is appreciated

    Thanks in advance

        Ph is one of the most common problems and would be my guess.

          Texasbob I agree, but not all in this case, pics 1 and 3 are burned, look like they are trying to flower, and pic 2 is going into lockout from bad PH, most likely caused by a feeding.

            You are probably right about 1 and 3 ! That is a really bad case of burning. Really bad. That is why I was leaning towards ph because it seems that corrective measures would have been taken before it got that bad. Imo

          I will say, learn how to build your own (organic living) soil (lots of info on the internet), you will be way better off! If your going to use bottled nutes, use the same brand for the entire grow. If you must use bagged soil, ask questions here as to what works best (I build my own soil)
          Read the posts here, and look at the guides, it will only benefit you! And keep asking questions.

            Awesome. Thanks! Will check the ph and feedback. Yeah I'm using bagged soil (premium lol). Another suggestion was to use canna 13/14 which I did and saw some improvement

              Hi, so my ph is about 6.3, 6.4 for the plants in bad condition and about 6.9, 7.0 for the better plant. I'll adjust up for the 6.3ish plants

                Is that ph taken from your run off? If not next time you water catch the run off in a tray and check ph. If above 7 then hit with a lower ph if below 6 higher ph. When you check run off if your not sure just post what the ph is and someone will be able to tell you what level you should ph with.

                  Imo it's overwatering it can and does look like nute burn and ph issues. With you saying you have changed so many things with the same outcome I think you are loving them to death which normally starts with overwatering... checkout this link it explains what I'm saying alot better than I can....

                      If you're adjusting your water for a better number for runoff - well - that's your choice. I have never checked my runoff.

                      My opinion - your grow medium looks awful.

                      You have the same medium for all your grows? That haven't really produced much? I would use a grow medium that isn't as hot.
