    Deficiency Or Nute Burn?? :(

    Hey guys,

    I have a few leaves on multiple plants and was wondering if i can get some assistance identifying the issue.

    I am growing in a 3/4 Perlite 1/4 vermiculite mix,
    Growing Using Canna Flores Moderately 2ml a liter (Recommends 2 or 3ml p/l)
    With A PH'd Water Flush Every Second Week

    No other nutrients used at this point and i am in day 5 of week 4 in flower.
    Any assistance is greatly appreciated

    That looks like magnesium deficiency, but the Image Reaper thinks I'm usually wrong, so what do I know?

    The clear close up of the damaged leaf is a good shot, but it would be better if we also had an image of the whole thing, so the damaged areas could be seen in context of the overall health of the plant.

    Which Canna formula are you using? The Hydro or Aqua formulas should buffer to a significantly lower pH than 6.5.

    Are you using anything to maintain trace elements, eg seaweed?

    I'd say it's a toss up between trace element def. and high pH.

    Hey Sarah, thanks again for you input in one of my questions lol

    I am using the all in one range Canna now makes, i'd have to check again which PH exactly it sets at but i think it was around 6.5.

    I'm looking at 4 different plants in that small area and they are all suffering symptoms. I think i may have accidentally mis measured some fertilisers i made and thats why those 4 plants were affected and no others as they are a few more which i used a different bucket for

    Thanks Guys

    Sorry not to get back sooner Tristan, I lose track of threads sometimes. You've probably worked it out by now, but I'll say it anyway. Canna's all in one is a soil formula. That it in itself may be the reason for the poor performance.

    Hope the problem is already resolved.
