    Default nute burn?

    Hey guys it's my first grow and things were going great until now ill give abit info on what i have:

    grow unit - wardrobe
    lamp - 250w hps
    fan - 3 foot lamp
    mylar


    the plants are baggy seeds so dont know the strain but please tell if you do!

    they are about 5 weeks into flower with the light cycle 12/12 on a timer.
    i've fed them at start of flower with miracle grow but was advised not to use it so i changed to biobizz from a friend and have been feeding them 1.5ml of biobizz per litre, plants being fed 1 litre every 3 days with the fan on constant.

    Very unlikely to be nute burn if you're only using 1.5ml / biobizz a liter.

    Possible nutrient DEFFICENCY though?

    I'm sure one of the more experienced guys will come along soon enough to sort you out mate.

    youu are using bio bizz bloom aint you?
    bio bizz grow 1.5ml / litre is too much

    but if your using bio bizz bloom then up it to around 3ml for a couple of day , then up it to 4ml
    but using biobizz you will need to give the plant some epsom salts mate
    youu can buy it from chemists too
    the recomended dose is 1 table spoon to 10 litres of water
    so half a table spoon to half a litre and so on.......
    but i noticed that you didnt use biobizz all the way through
    and mate i carnt see the pics very good because of the hps light but looks to me like you have a thrip problem
    llooks like you have damage on your leaves from thrips
    in the 3rd photo on the bottom left looks bad
    do they look like this or simular to this with the silvery marks?

    Agree with the epsom salts, its worth trying them, just incase its a mg deff (doesn't look like, but who knows, no harm will come of it).

    Not to sure about upping the dose, they are getting 1.5m/l which SHOULD be enough not to cause any deffiencys, i'd hold off until you have fixed the current problem, adding more nutes woulden't help nessesarily I think.

    As it seems to not be a thrip problem, I guess your still going to have to wait for one of the 'older growers' mate.

    But you don't have to long left in flowering, only a few weeks, maybe its not worth the effort finding, and fixing this problem.

    not sure how 1.5ml of bloom can be too much, i use bio bizz myself
    ive used batmix soil and bio bizz soil
    i give mine 4ml / litre during flower and there perfect
    i also put 1ml grow in with that he first 2 weeks in flowerr
