    Hey everyone I have one girl flowering everything was great until last week when I notice yellowing with brown spots

    I’m in a 4*4 tent with two hlg 260 setups

    Nutes are the fox farm trio with molasses

    Soil is fox farm happy frog mixed with strawberry fields (all I had at the time so had to mix both bags together)

    Temp is always 73 and 64 at night
    Humidity is 39 most days

    This happens to me a lot when week five comes around I always have yellowing

    Any insight into what I did wrong or what I can do to fix or should I just ride it out

    My run off measured 5.8 might that have something to do with it?

    Could be causing some lockout. Aim for 6.5 in soil. Little higher doesn't do too much harm. Below 7 tho

    I'm getting better results with this pH range than my last one which I kept 6.0-6.5

    No nutes. Just water pH 6.5-7 flush
