    Default Stunted growth of 4 plants

    Hi guys,



    Got some problems with my plants. They are growing too slow. Here are some info:

    Green label: Skunk XL
    Blue label: Amnesia haze
    Pink: white widow
    Small one in the cup is also white widow.

    Planted on 31 of Jan straight in canna coco natural and they sprouted 2 days after. They are under 600 HPS dual spectrum lumii light.
    Im adding rhizotonic and canna A+B.

    At the start I had problems with temp 40C and PH which was really low as had shit ph meter, now temp is about 27C with lights on and watering once a day 250ml each plant 6 ph.



    Got no fans at the moment and they started in the last final pot but I think they are too small for their age anyway.

    They actually started growing since last week but are too small for their age.

    Anyone can have a look and advise?

    P.S: small one looks like it is dying

    Good morning. I don't have much experience myself, but i feel you. I also feel like i have stunned the growth of my gals and i also planted mine on Feb 1 , and they are growing slow. some Parts of my mistakes were the following : not proper PH, and watering too much. Also, the light distance was farther than they should .Well, 250ML everyday sounds like a lot to me( based on their size) ,although a more experienced keeper will help you with that. BUT, i found out that besides the right temp (40C sounds like an important factor that may have stunned them ) , i had a very low RH. I got a humidifier to keep it as much as possible to 60-70% humidity .i've heard that this is the ideal RH for seedlings at this stage. As soon as i got a humidifier i feel like there's a 'visible' growth each day. The cup the little one is in, the water looks like it can''t evaporate ( if it's always like that), did you try to open some holes on the side? also, are those photos? if so, shouldn't be on a smaller pot and then re-pot them to their final?
    again, don't count on my words as i'm a newbie here. Here's some questions to answer in order to help the others help you .
    1) RH :
    2) Light distance:
    3) Nutrients fed:
    4) pot size:


    Wish you luck with your girls

    Your ladies are hungry.

    What is your EC & pH ? What is your feed schedule?

    You need to be feeding once / twice a day to 20% run off. EC 0.2 / 0.3 at this stage at pH 5.8

    Hi,
    Im using a+b canna 5ml each for 5ltr bottle and 20ml rhizotonic.

    I am attaching picture of my ec and PH pen, seems too high but my base ec is 0.45, tap water.

    Im watering 250ml a day and using only water with nutes. Should i also use plain water?

    I am scared to water till run off as they are young so if they are in big pots roots wont breath.

    What do you think?

    How can the EC & USCM be so different?

    That said, An EC of 1146 isn't a valid reading

    Throw it away & get a proper EC pen mate

    Damn, got no money for new one now.

    Probably I can buy it next month.

    In the mean time what can I do to fix it?

    I mean EC should be good as it was just calibrated before taking a picture.

    First grow is much harder that I thought. Hope next one is going to be good

    So long as you understand the numbers that is all that matters... my EC meter reads from 0.4 - 5.2

    I'm assuming that you take your number & move the decimal point 3 digits to the left for EC? (1146 becomes 1.146?)

    Correct bro. Is it too high if my tap water is around 0.4-0.5? Or should I keep it this way?
