    How big is the pot?

    How much and how often are you watering?

    I could be wrong, but it looks like Nutrient burn, so don't adjust your spring water with acid, and reduce your nutes, (formulex Baby plant NPK formula) and (cal-mag). If it doesn't get better soon, then transplant into a new fresh soil or larger pot. That's just my opinion and some of the other guys can help you with some better suggestions.

    JMO - but I think it's a watering issue - I thought it was going to be over-watered but if you're only watering once a week, then she's possibly under-watered (tricky to tell the difference sometimes)

    Like creeper says above, no need to adjust yer water.

    Did the yellowing start before you switched to 12/12? Soil will adjust water PH-no need to do it

    you might find the "bottled water" is in fact just filtered/RO water in which case youll have been leeching the micronutes out of the plant.
    plus possible same water contains no micro and so your plant isnt getting any.

    last-latest growth seems to show theyre lightening and starting to get hungry,they look as though they could do with a tidy up down below to let the oxygen flow freely.
    fraid theres still the bit where you know more about the grow than we do so itll just be stabs in the dark mostly i think,theres still an entire grow enviroment we know nothing about.

    i dont know that feed so dont know if youre doing organic or chem grow but theres plenty of info on both in forum.

    atb,good luck with grow chap.

    Strain: good old bag seed for first try

    Photo or Auto: photo

    plant age: sprouted around 20/21st december 2018

    pot size: 8.7L

    has it been repotted? and when?: 2 weeks ago maybe a little more

    soil type: verve seedling and cutting with nothing added (i know i know)

    nutes or additives used and how often for soil: the nutes i HAVE are (Growth Technology Formulex 2.3,0.9,3.4 - vitalink calmag - canna rhizotonic - canna boost - dutchpro multi total - bhuddas tree ph 9-18 - groth technology ionic soil bloom). i started them light on a little rhizotonic, then have been giving half dose feedings of the formulex every water bar the last one. watering weekly i havent got the best drainage but i killed 2 plants yesterday and there roots were pretty white. the soil from the bottom of the pot squeezed out about 30ml water from one handful if that helps at all.


    Air temps (max min): daytime were 18-21 until a few days ago when i finally was able to get them up to 23-26. night temps dont drop too much maybe max 6/7 degrees c

    Light schedule:was 18/6 now 12/12

    ph level: adjust to 6.3-6.5, lowest ive fed is 6.2 highest 6.5

    Background EC.

    feed schedule and nutes (for hydro and coco)

    yellowing sstarted around 3 days before 12/12 but was not progressing until one night then boom it was bad lol. the plants are very small, the yellowing affecting the lowest growth. i suspected nitrogen deficiency after looking at loads of puctures.

    Anyone can burn a plant early in a grow. You can burn the leaves on week 3 and it will show on the leaves the whole grow and never be burned again. Just transplant them into a new pot with fresh quality good soil. And Water as needed! You will be alright in the end.

    Are you talking about yellowing at the top of the plant? The new growth at the top doesn't look yellow to me. It looks exactly like new growth should look.

    How far away is the light from the top of the canopy?
    What is your watering technique? Fast or slow?
    Have you started using tap water?..that'll be fine in the UK.
    What do you mean when you say you haven't got the best drainage?

    Can you post some more pics of the full plant?

    hi, i would say due to small pots with no perlite and once weekly watering the plants are getting hungry, this hunger is pulling from those lower leaves. i would take those bigger fans off below. Repot to 15 ltr air pots or standard, make sure to add around 25 % perlite and try to get that into the older soil too. I think a simple repot as the lads have said would sort it but do use perlite ok....

    water - why use bottled water mate? Get ya plants on tap water mate, full of micros they need. Its all very well having cal mag but they need the full spectrum of micros not just cal mag. If you tell me the ph and if poss the ec of youre water without any feed. This will tell me whther you have lots of rock salts in there or not.

    Ok regards ph adjusting - stop it dead. repot the plants, when you do get some great white shark and rub it all over the roots when you pull her out the old pot. This will replenish any micro herd you damaged with the acid......Tip when the grow is back on its feet and you have repotted and used great white shark, you will want to feed that microherd (black strap mollases ) to help make them excited and make nutes availble to the plant. They will buffer the ph to where ever the plant fancys for dinner tonight..perhaps a bit of p, no actually k tonight lol....serious stop ph'ing it will lead to head aches trust
