    Question Deficiency and problems with autoflower girl

    Hello friends.

    Im having an issue with one of my autos. Its a Quick One from RQS. The soil is All Mix (I know, should be Light Mix), in 25L air pots. Im using only BioBizz products, and Im using all of them, in a conservative way. Watering every 4-5 days. Temperature, humidity and air flow is good. However, about 3 weeks ago this plant started to yellow and turn pale from the tops, and then that went to all the plant. Now, it has some brown spots on some of the leaves. She almost stopped growing, and is not flowering (should have flowered by now). Please see attached pictures.
    Im guessing this could be a cal mag defficiency, but Im not shure.
    Could anyone help me please?
    Thank you in advance

    I dont have a PPM meter, but I can tell you me feeding schedule:
    (All products are BioBizz)
    BioGrow - 1ml/l NPK 4-3-6
    BioBloom - 1ml/l NPK 2-6-3,5
    TopMax - 1ml/l
    BioHeaven - 2ml/l
    ActiVera - 2ml/l
    AlgaMic - 1ml/l
    The PH of the final water (after nutes added) I feed is around 6.3 - 6.5.
    Btw Im running 2xSP250 lights from Mars Hydro.

    Have you grown before? I've only got 1 under my belt but I didn't nute in veg and in flower about 2ml per ltr of canna bio bloom and 1-2ml bio boost. Was advised autos don't like boosters so dropped boost and one probably didn't need any bloom nutes at all. There's one guy who's last grow went from seed to harvest in just soil. With you, Overkill maybe? Be plenty drop in for a look mate so soon see what the crack is

    No. Easy Bud is another strain. Had it once and it went good. The quick one Im having for the first time. The other plants are looking great, and all of them are having the same treatment.

    orgaincs can be tricky, bio bizz lacks mg imo and that is a mg def, dont chuck calmag at it just mg , is that under led? if it is keep the room temp at 28c and give extra mg every feed and she will green up again some damage wont repair

    I've found a foliar spray of Epsom salts, as autos finish their stretch, a way of preventing this

    Forest gave me the same advice,took about four days from very light green to a healthy dark green, works a treat, it makes crystals stand out like a fall of snow (my white Christmas)thanks Forest.

    I'm not a fan of Epsom powders but many use it and at one table spoon a 5l so ur about right
    To low Temp will lock out mg under led . Wrong ph will too
    What the canopy temp?
