    Default Calmag deficiency I think

    Only me again people this is me northern lights auto just over 7 weeks old in a 12 litre fabric bag with canna terra soil an perlite
    Under a led ish 265 pro about half a meter above the canopy thats on 20 an of 4 temps are 20-27.c humidity between 40-60%

    Have gave them one small amount of dutchpro root about 4 weeks ago then a small amount of emsom salts about a week later

    then 1ml of dutchpro a&b bloom an a half ml of dutch pro explode about 4 days ago an that's all i have gave it so far

    From what i can can work out it looks like a calmag problem but i could be wrong maybe starting to get abit hungry aswell an with led plant's need extra mag from what i was reading but im still a noob so cant say 100% lol

    If anyone could help me in the right direction i would really appreciate it i have been looking into getting some calmag that i can add to the soil just not sure what to use if anyone has used any of the 1s in the pictures or know of any others that would really help cheers

    One thing to note with calmag is they are generally high in Nitrogen and can throw your Nutrient Element Ratio out of whack quite quickly.

    There are a couple available with lower N values. General Hydro calmag is around 2-0-0 and their CaliMagic is around 1-0-0

    NO SELL, NO SMELL, NO TELL!!!

    It could be your LED.

    I have had those rust spots too under LED when there should be no shortage of cal mag.

    Not sure what to recommend! The problem that my plants had went away on their own.

    Calcium deficiency

    Like val mentions if the leds are too close and local humidity is low from fans blowing on leaves, plant gets evaporation problems.

    Calcium is very mobile so it needs to get up to those colas quick time if the evaporation is quick and sometimes there isnt enough.

    I do and it stopped my issues very swiftly...once I had the dosage sorted.

    Calcium excess in 2 hours using the instructions on the bottle.

    Went down to the tip of a syringe and no further cal or mag problems at all.

    I rate it.

    Seriously, though....if ever there was a "less is more" product, it's MagneCal.

    When you do things right, people wont be sure you've done anything at all.
