    Default Nutriment burn ? Azote, Magnesium deficiency ?

    Hi everyone,
    I'm Seuty and this is my first session.
    That's why I have some problems, I think that I had 2 burn nutriment since the beginning (Even if I used to put less than half than write on the instructions)
    I flushed all my plants 10 days ago (then turn my light 12/12) and after 7 days, my top leafs began to turn yellow (from the middle of the leaf). I thought that I had a Magnesium, Fer or Azote deficiency so I decided to give them fertilizer + magnesium sulfate, but 3 days after it's still becoming worse (the leafs turn Brown from yellow). So I dont know if it's a burn nutriment or a deficiency

    18°C/23°C temperature
    50%/75% Humidity
    Frequency watering : 3/4 days
    380m3

    I'm very concerned for my plants I ve spend a lot of hours to find a solution but Nothing.
    Thank you very much for your help.Click image for larger version.

    What pH are you watering at and what medium are you growing in?

    Coco : Ugro coco pure - it's suppose to not contain any nutriment
    I use :
    Canna COCO B ~1,9/L
    Canna COCO A ~1,9/L
    Diamond nectar (GH) ~ 1,0 /L
    BM Trichoderma harzianum (GH) every 3 weeks

    HPS 600W
    PH 6

    the problem is that since the begining my EC drain is to high and I dont undestand why (10 days ago my EC drain was 2,5 wereas I have never put more than 1,2)
    Whats more I loose a lot of leaf from the bottom

    thank you for your quick answers.

    thank you for your quick answers.
    I've only run coco a few times but that all sounds OK to me, what's your feeding schedule? With those leaves and lower leaves dying it shouldn't be too difficult to identify the problem.
    There are a lot of very good coco growers here that will see this at some point too.

    You're growing in coco but only feeding every 3-4 days? Coco drains/dries very quickly, you should be feeding daily!

    Look like they don t want to eat, last time I did a drain water (without any nutrients), it took 7 days to be dry
