    HELP! Yellowing leaves

    My greenhouse grown OG Kush (feminised, photoperiod) has grown like a weed (!) but over the last couple of weeks some of the leaves have started yellowing.
    There doesn’t seem to be any pattern to the yellowing - photos attached
    I appreciate it could be a number of things - over watering, irregular watering, temperature changes, insufficient nutrients, too many nutrients, root pH, but I’d welcome the forum’s opinions
    Please be nice, this is only my second year growing!
    It’s being in grown multi purpose compost, in an air pot.
    I’m feeding it with a general purpose feed

    Good morning Redtomato were all nice here....usually. Nice looking little tree. As the plant ages they will start using nutrients from the bottom shaded fan leaves to fuel new growth and flowering. Yours are just beginning the process.

    Finished Grow: Critical Mass photo - fem x 3 plus 1 clone same

    Space: 30x48x62 DIY cabinet lined w/space blankets
    Lighting: Bloomspect SS1000 Quantum board x 3 - 300 watts actual draw total
    Soil Supplements: Worm Castings, Guano, Crab Shell, Oyster Shell, Neem and Karanja Meal, Volcanic Basalt Dust (for minerals), Recharge root micros, ACV for organic pH down as my filtered tap water runs over 7.5 pH

      Thank you TOKABIGONE! Is that still the case with random, different size leaves elsewhere on the plant?

      As long as it's not in the new growth it's pretty normal

    Nothing to worry about ! Really nice looking plant. Second grow - that is really good 👍🏻
    Good job
    Just because people are over 50 doesn’t mean they know everything.
    You can teach a old dog new tricks - But it will still think the old ways are the “best” lol

      She looks pretty good over all. I'd add a little cal/mag to her diet. What is the NPK value of your all purpose feed?
