    Default When to use p.k. 4-8?

    Alright folks, can anyone advise me on when to use p.k.4-8 nutes.
    I think I've probably got about 4 weeks left to go in my grow. I've been using oldtimers organic range of nutes grow/bloom and I'm not sure when to use the p.k. . Should I already be using them? I haven't got a clue.
    Thanks

    Ok mate, thanks. 1 more question though. How long for? I'm under the impression there's no need to flush when using soil/organic nutes so should I use until chop or stop a week before and flush anyway?

    I generally use pk 4 weeks after flip. I use all the way until flush.

    I dont know about not flushing in organic and with soil. I would imagine you would still need to though. The plants turns chemical or organic nutes in to the same stuff in the plant. These nitrates will still need leaching out of the plant before harvest.

    Id check up on the flushing business tho, I've not grown cannabis in soil.

    I have grown a lot of veg in soil tho, and I know I've always had to flush that.

    I use PM PK and I start it 4 weeks into flower for 4 weeks. You will be ok to use up until chop. No need to flush.

    don't need to actually flush the medium in organic, last week(s) feed just water instead
    have tried both flushing and feeding just water, makes no difference to the taste when growing organic since it's not salt based fertilizers

    pk 4/8 feed when the stretch has totally stopped until the only water feeding at the end,
    1.5ml per liter is plenty especially in organic
