    Why this lady going to yellow?

    Hello one of my ladies turning to yellow since two weeks on blooming stage. There are other strains on the same room but not like her. I mean they're all good. This one is a little strange from the begining. On veg stage she was so slow and not developed too much.
    It looks like ph is ok (for watering test). I'm also adding CA-MG as scheduled by the manufacterer. How can I stop this? If I cant stop the process Is better to make an early harvest or Can I wait until the plant give up by itself?

    Hello vincenoir some strains need a 1/4 to 1/2 normal amount of N during early flowering still. I have one that looked similar to yours it started with using full on bloom nute without any N in early flowering. I flushed it real good to run off then allowed it to dry a couple days ( it's warm here and dry) then gave it some Epsom salts few tablespoons per gallon of water with some guano/fish poop tea. I will stop giving N with the bloom as I see the plant reaction and then it's natural for it to yellow up late in flower. Roots get hot in plastic sometimes we overwater to compensate flush out soil nutes. If it's too hot move into shade for few days to recoop. My 2 cents Goodluck

      I agree it looks like Nitrogen deficiency.

      Hello soorbudgal! Thanks for your quick reply, It was so illustrative. I'm going to stop giving any N to her until getting a good reaction. Its a little warm and hot here too. I was adding Seaweed to their water for reduce the heat stress. Should I stop that too in flushing process? By the way what do you mean leaving in shade? Should it be on natural room light or total darkness? I guess the first one right?

        If you see no benefit from added N. Check your soil for very tiny bugs.

          I think there is benefits of N. I checked the soil and I didnt see any bugs. I use a spray called Biobizz leaf coat for bugs.

        vincenoir, are you giving them any nitrogen? I have two autos that are VERY picky about their Nutes. Have 8 plants all into flower and two of the autos did not like the nitrogen %, went real dark,started burning tips, so i cut them off of nitrogen for two waters...wasnt a great idea..started looking like your last pic of the leaves. I eased some nitrogen back into water schedule and plants are much better now.

          Yes. I use Aptus products. In this stage I use Topbooster, Super PK and Regulator. I was planing a flush with epsom salt as SoOrbudgal mentioned on second post. Do you think It doesnt worth to try?
