    So the description says it all my plants are green and beautiful during veg but lose their green a week into flower any thoughts? It's not really effecting the harvest to much but I know if I could keep them green threw week 6 or 7 of flower they would be better.
    Nutes:
    Botanicare bloom
    Cal mag
    Sweet
    Liquid karma
    Silica blast
    Hydroguard
    Hydroplex

    Sonic bloom
    Bud factor x
    Big bud

    Not really sure, maybe it'll point you in the right direction but you wanna keep feeding veg nutes until the stretch is about done then wean into flower nutes. Point being maybe it's not getting enough for the stretch. You should really post pics tho for others to help you cuz yellow could mean anything, picture is worth a thousand words in this case.

    .. talk about your transitioning-to-flower nutrient regimen ?

    I've always thought you wanted to keep grow feeding the first couple weeks. But never had so when should I transition to bloom regimen

    I'm a newb so take it with a mountain of salt but that kinda sounds like the ones that stretched more and are green had enough nutes and the others didn't have enough so they didn't get as far or tall, individual plants of the same strain can need different amounts but especially different strains can be picky so x is enough for 1, burns another, yet starves the third just for an example.

    Same issue last harvest but we still got really good stacking and final product

    After stretching stops I believe, others should know better but pretty sure that's the right call

    Same nutes and ppm for all

    If you got different strains they'll likely have slightly different needs, might be thinking of hydro cuz it's much more apparent, but look up what deficiency looks like (there's a lot of different kind) and go from there. Like I said I'm a newb just burned so much info into my brain, I'm spitting back articles and threads.

    None of these pictures are 1 week into flower where you said the yellowing starts?

    So the plant in the top picture looks normal the middle picture wouldn't load and the bottom picture looks normal that purpling might be genetic or cold induced not really seeing what you're talking about from those pictures but maybe somebody else does -good luck

    Also they look very light green rather than yellow, yellow would be like dying leaves falling off type thing (edit: deficiency isn't just ppm it can be a specific nute, the stretch likely uses a lot of nitrogen which could also explain why the leaves are yellowing as a lot of N is usually dark green coloring and not enough means yellowing, just general examples as I don't have the experience to back it up, just give ideas and point you towards what problem it may be

    not all plants are the same, some have much higher nute requirements than others, and the first few weeks of flower is when they're the hungriest. you should keep feeding veg nutes till the buds set and the stretch is about over, but you should feed it at a substantially higher rate, the plant is growing like hell, and it will eat itself if you don't feed it.
    this doesn't apply to all plants, but if you see one even beginning to fade that early, bump up its feed rate immediately. on a number scale, in veg i would feed 3 or 4, during the stretch and the first two weeks after, i'd feed at an 8, then i'd start dropping it weekly till i was back down to a 2 or 3 at the end.

    So if my max ppm af the end of veg is 1360 I should boost that ppm up to 1600 or so with same regimen as veg?

    yes, IF the plant seems to need it. i always bump up feed during the stretch and the two weeks after, but how much depends on what the plant seems to need, you can't assign numbers and use them for all plants.

    Flowering don't technically begin until a couple weeks in when stretch stops and bud starts, so consider it veg until that point

    ^^^^^

    All this plus I don't know your products, I use General Hydroponics 3 part but I go from 3-2-1 veg formula to a 2-2-2 transition-to-flower nutrient regimen for anywhere from two weeks to a month, as Rodger said feed that plant when it wants to eat the heaviest, and I suspect you may be going to your flowering nutrients too soon, possibly why you're yellowing too fast ?
