    8 days old seedlings turning light green - yellow

    Hi all, quick bout me:


    second time growing (first one was from clones, this one from seed)

    600W hps --> light is hanging bout 60 CM above plants
    18/6 cycle

    Tent (homebox)

    Temperatur - about 27-28C

    Humidity 50-60%

    Not feeding them nutes, only 8 days old

    Growing in COCO

    Ph in water: 5.8~




    ahh where to begin.. okay so i germed 6 critical mass + 3 LA woman + 1 Fem Sleestack + 1 smthn else and i realized i had a shortage of small pots (dummmbbass) so i used some DIY crap pots i made..



    at day 4 i see that 1 of them are getting pretty light green (and a small small yellow spot on the end of one of the first true leaves.



    at day 5 its getting more light green and 1 or 2 follows..



    at day 8 (today) 6/10 are going light green on me.. no more yellow spots tho..



    I repotted to bigger pots, i dont think they where ready to be repotted but im afraid those DIY pots contained alot of water at the bottom so i switched them..
    Im watering with 5.8 ph <-- is this the problem?
    im not sure if i want to read PH in the soil when they are this young, i mean its really fast to be overwatering them right?

    any ideas?



    edit: I actully dont think im overwatering them, only giving them a small amount of water and wait until first inch of the coco is dry then i water some more..

    i think i water more often then others but alot less.. so easy to overwater and then panic and water some more lol

    Not that i know anything about growing in coco'.. but i see 2 lows'.. your ph and your light' unless you have a light spreader fixed to your light or its air cooled i wouldnt have it that low for 8 day olds'.. and your ph im sure should be 6.5 or around that mark'.. hope thats some help'

    ive been googling all day long and i think that yes

    i really f****d up on the PH! going to start watering at 6.5~

    when should i lower the PH and how gradually should i lower it?

    about the light hanging low, i did have the light bout 1,2 meters above b4 but it seemed that my seedlings streched alot.. 2 of them stretched really far.. so i decided to try to lower the HPS, atm it seems fine and temp by the seedlings are 25-27C messured in the shadow of some cardboard at the same hight as the seedlings. i checked temp yesterday "in the sun", no shade, and it showed 32C im not rly sure wut to think bout this? wich is the correct messurment? wut shud i trust?

    Give it a good flush first adjust your ph to 5.85 with 100 ppm. Dont water for 24 hrs and then start feeding. Only use 1/4 of your nuts!
    Good luck

    Correction!....oops Im sorry I'm ADD plus high, lol. But here what u need to do.
    1) 8 day old lill dingling dosen't need strong light. 60 W CFL daylight will do the job very nicely. You need to give it a chance to start the new roots. Adjust your ph to 5.85 with 100 ppm.
    You will be good to go. I will post a link for you later on which it will give you a good idea how to grow in coco.
    Peace
