    Hello peeps,

    looking for abit of advice with my HSO black dog og.
    I’m in small cupboard, it’s my 3rd grow in here but it’s the 1st photoperiod Iv grown.
    Never had a problem with my growing method or environment Before but all my plants seem to recive a small amount nute burn.

    Iv got a black dog og on week 9 I flipped to 12/12 at the end of week4
    I feed with tap water the ph is 8.2 out the tap

    This strain has a short flowering period of 48-55 days

    So she shouldn’t be to far from the finishing,

    After some reading about the biobizz schedule is for rooted cuttings not seedlings I started to back off on the concentration of my feeds! Everything was still going going but llast week I notice some leaf tips going orange and pointing upwards, it’s got progressively worse over the last week but only effecting the some of the Leafs through the canopy, and growth has slowed

    So I’m torn between thinking that my feed that I give her in the earlier weeks of flower was to strong and being organic I’m only now seeing the consequence of it? Or Iv dropped my feed concentration and that’s higherd my ph locking out some goodies? I’ve looked through deficiencies and it looks kinda like a (P) but I’m not convinced.

    I know that there won’t be a miracle fix for this, I’m just looking for a wise compromise to help me limp over the finish line.

    Thanks in advance!

    Photos coming ASAP!
