    Default Not looking good after last feed.

    Hi guys! Hope you can help me.

    Problem: The honeys were good until 3-4 days after feed (1) My plants are Brown at the edges. Fan leaves are loosing colour, feel dry and overall you can see that leaves start to look unhealthy. Also the leaves curl at the top.

    My thoughts:
    I think I spot phosphorus & maybe potassium, nitrogen deficiency. Therefor I suspect a
    Nutrient locksdown. But why? They were looking good all time untill last feed. Ppm is not that high
    Also I know that phosphorus disintegrates slower in low temperatures. Could that be a problem?
    Is my best call to flush ?


    Feminised seeds: Sage’n sour, Mk ultra.
    Week 4 of flower
    Temp 22C / 17C,
    LED lights
    Ppm in last feed, arround 1000 / Out came allmost the same amound.
    I Use vinger for pH down.
    pH: 6 +- 0,3
    15L textile pots, soil

    Biomix everytime They get water.

    (1) Last Feed ml / L :

    3 Bloom & Grow
    0,5 cal/mag
    1,5 Algamic

    (2) Feed before that
    - Everything was good here, maybe lighter nuance in 1-2 lover leaves ( only Sage’n sour) but for a longer period and no deficiencies like now, on all plants.

    2 Bloom & Grow
    0,5 cal/mag
    1 algamic
    Ppm in 750 / out 830

    Hi Max

    I hazard a guess at nute burn going on the burnt tips and clawing of leaves following you upping the dose on last feed

    As you are in flower, the bottom leaves and any other leaves would have already started to feed the plant and will show quickly when the feed is too strong I've found.

    Just a thought and maybe back off on the higher nutes for next feed and maybe a flush might be needed if they continue going downhill.

    Thanks Petal.
    Its good to hear the openion of others.
    At this point Im thinking to back down the nutes and flush once.
    After that adding a feed like feed (2)

    If you can avoid flushing during flower would be better but if unavoidable then introduce your feed at lower doses initially - you'll still want your flower nutes and during this time of adjustment the plant will be drawing on what's in the leaves.

    All the best.

    So some two weeks after, my plants look like this.
    I wanted to show you guys the aftermath.
    Maybe someone could indentify my plauge?
    After my post a did a Mini flush and backed down on the nuteS.
    2ml/L Bloom and grow is What I am feeding now.

    One of my plants has Brown dots and edes. The leaf feels dry and a pice of the
    Leaf snaps off when I pull.
    I would really like to know What caused this, so It wont happen again

    Hi
    Yes, Im using soil.
    Tapwater is arround 330 ppm.
    Light distance is 30cm. This works because I had good results
    Befor. My other plant is even closer to the led, but it
    doesen’t have same symptoms.
    Led is viaspectra 300w ( arround 150w)
    I have a fluorescent bulb only 15w close to the sick plant. (5cm)
    But Im quite shure that tis is not the problem, the deficiency is immobile

    Its the same problem you been having for nearly 3 years. Your phing the water and not following manufacturers instructions or advise.

    I have personally used the V300 and Biobizz for several grows and they are a great combination.

    Biobizz buffers soil ph and you dont neeed run off or to concern yourself with EC just follow their guidelines.

    Questions: 300ppm makes the water hard, right? Why are you using calmag?

    Why are you pH'ing the water down to 6.0 in soil? What is the pH from the tap?

    When you say 3 bloom and grow...do you mean 3ml/L of each?
