    This has happened with most of my growers around the same time. The leaf tips start to burn around 3 weeks of flower. The yield always ends up average to good but I wonder if it would be better without the minor burn. Ive also lowered my feeds the last 2 grows and it still happens. Can you take a look?

    plant looks great man, I've learned that slight fertilizer leaf burn is almost a good sign. That means you know now how much your plant can take. If this issue gets worse keep weakening the strength ever so slightly not too much because deficiency is worse then slight fertilizer burn.

    Or try flushing before fertilizing next.

    1460940650530.jpg 1460940670791.jpg check this out, it's starting on a few leaves. My ppm is down to 558, wonder if it could be heat stress. Runs between 75 and 82

    Remember that your plant will push energy from the leaves to the buds during flower, especially if their nutes are not strong enough. I've seen plants with horrendous looking leaves at the end bud but great buds. I'm a proponent of lower nute strengths but I have plants in week two of bud that I'm feeding at 1000 ppm and they are loving it. Each strain is different in this regard. Maybe try increasing to 800 ppm and see what happens over the next two weeks.
    Overall however your plants look great and I wouldn't stress minor issues like this.

    Btw your temps are fine. They won't stress at those levels

    He was correct although ppm of around 720 fixed the problem. I added a little more calmag.
