    Ok so tap water after it's been sitting for 48hrs or so nutes GH trio and some mirco nutes I just stopped Big Bud soil is promix
    Temps are 30c day 25c night RH stays from 20 to 35 its northern lights and had a mutation where the leafs curl inward thought it was fan burn but turned out it wasn't it was this mutation that's only on one side of the plant. It's about a month or month and a week in flowering no pests no nothing she was loving life until about a couple a days ago I noticed those brown spots last time she got any nutes was April 15th and before that April 2nd so I'm not really leaning on over feeding I'm thinking maybe under feeding.. Any ideas

    Looks like heat or wind stress to me. Where's you fan? Does it oscillate?

    Maybe a stupid question but are you using fresh ph calibration solution? I met a grower that was reusing the solution causing faulty calibration. Gotta make sure ph is where it needs to be before trying to find other problems.

    Give it some feed , promix, has some feed in it, how old is the plant. My guess is you are outgrowing the feed that is in the soil at this stage.
