    Hi guys,

    I have a major problem that i dont really know how to fix, and to be honest i dont even know if it`s a problem.
    I am growing

    Big Bud from Sensi
    The plants are flowering, they are in the beginning of the 7th week.
    NFT system
    400W
    Using Canna nutrients
    PH 5.6-5.8 almost at all times
    Relative RH - 40-45%
    Water temp 21-22 Celcius
    Indoor temp 25-29 Celsius

    The yield seems to be unimpressive so far, but from what i can see on the buds they havent matured yet, so they will need an extra month in my opinion, because they have streched until the 5th week.
    I`m really dissapointed with the strain, but maybe it`s my fault, first time grower.
    Anyway i attached some photos, maybe you can share your wisdom and help me get a yield, any yield.

    Thanks guys, i really appreciate it.

    Curling can be due to a number of things. PH, heat, N toxicity, nute lockout. I assume you have changed the res. I would feed lightly in 6 PH water, watch for overheating and hope. I can't figure out what is up with those lower leaves/stems. They almost look like they were frozen. Weird.

    I'm a soil guy but what EC/ppm are you adjusting to? I feed at 1-1.2 weekly in promix. It looks like nutrient shock to me. Leaf curl up is nutrients.

    I`ve been feeding the plants from 1.2 to 1.6 EC.
    I tried 1.2 to see if it`s nute burn on the tops, but it`s not that.
    The top of the plants dont have access to light, could that be it?
    And it`s not overheating from the bulb either.

    I would try soil for your next grow. Spend your money on lights and ventilation. Keep your nutrients as simple as possible. Get a few grows under your belt and then expand your nutes with your knowledge. Grab a clone if you can. I would also try an autoflower depending on your setup. Enjoy!
