    Pics lower down.

    What type of medium; soil or hydro?
    Soil

    What brand and type of soil?
    Biobizz light mix 15L
    Perlite 2L

    Indoors or outdoors?

    What strain?
    G13 labs berry auto

    How old are the plants?
    8-9weeks old

    What type of lights and how many watts?
    Mars hydro 600w led (~237 actual watts)

    How far from the lights?
    ~11 inches
    What is your watering frequency and source of water?

    Once every 3 days so basically water on say a Monday then Thursday then Sunday etc..

    What, how much and when was it fed? NPK?
    To start all water is left over night and is then Ph'd down to ~6.5
    She has received some biobizz grow 4-3-6 and some calmag 1.8-0-0 in the past neither at full strength though. Past 4 waters or so it's been just plain tap water that's been left over night and then Ph'd down as I've been away and had someone tending the plants and kept it simple for them.

    What is the medium/runoff pH and PPM if in hydro?
    Unsure of the pH run off, will update with that tomorrow when she gets watered.

    What are the temps and humidity in the room?
    Temps~23c-26c
    Humidity ~55-60 during the day can spike to 70-75 at night though.

    What size pots?
    20L but only in 17L of medium

    Any bugs? Look real close.
    Pretty sure there's none, could be wrong.

    Any other pertinent info?
    She's sharing a tent with two other autos of different strains, she's in a fabric pot, she's growing at a good rate I believe just these tips must mean something's up?
    Some fan leaf stems have a purple/reddish tinge to them.
    The picture that is the big fan leaf that's discoloured what is this also please?
    If there's anything else I missed or any more pics you'd need to see then please let me know!
    Thanks!

    Nute burn, back off the N the leave's are to dark & the tip's are burning. Feed it more P & K.

    Purpleing stem's are very common, so no worry's there unless it was a P Deficiency caused by lockout.

    Older leave's die naturally during the flowering phase...

    I haven't given feed in about 2 weeks, just plain water and the tips I have bio bizz bloom which is 2.0-7-4 would that be okay to feed?

    Yeah you should be using the Bloomer, but you may be better off just just using a P and K Booster and let the plant eat it's own N out of the leave's. This way it wont taste like chlorophyll when it's cured.

    Little update if anyone can help please, plant is about 10 weeks now, I'm now up to 1ml per L of biobizz bloom (2-7-4) since last feed.
    Are the tips burning from this? If so what aspect is causing the burn? The nitrogen? IMG_20190627_105543794.jpg IMG_20190627_105554092.jpg IMG_20190627_105602187.jpg
