    Nitrogen toxicity - lockout

    @Onextremebuzz appreciate the input man, yes of course having a stable rez temp will help, but if i understand you correctly youre saying the water temp affects pH, but my pH is stable which ultimately is all that matters. Ive probably done 7/8 dwc grows now, obviously my set up/skills arent...

    Nitrogen toxicity - lockout

    Ok thanks. I grow autos, Im running my lights 24/7, as do many auto growers. So there is no fluctuation in water temps. But might be time to change that to 20/4 or 18/6.

    Nitrogen toxicity - lockout

    Sorry mate. Well that's what makes me think it's not a water temp issue, pH stable, 5.7 - 6.3. And when I use my ppm pen it gives temps, 18-20°c.

    Nitrogen toxicity - lockout

    Not sure about that, but ive done dwc in summer when the rez temps get really high so i know how that feels, i think the water temp is ok. Ok great yeah i was thinking something similar. So after topping her up with water yesterday shes now at 500ppm (my water is about 170) should i lower it...

    Nitrogen toxicity - lockout

    Appreciate the feedback gents. What i see now are 3 things 1) a bit of N toxicity 2) a bit of Mg deficiency and 3) beginnings of nute burn, leaf tips are looking a bit burnt. Yesterday she had 730ppm that dropped to 600 topped her up with water so shes down to about 530 now. Gonna give her a...

    Nitrogen toxicity - lockout

    Actually bro that was my other plant, i discovered my air stone was totally blocked so she was basically drowning which might explain why she was such a mess. Thats been fixed and she seems a bit happier with some proper bubbles in the bucket.

    Nitrogen toxicity - lockout

    Nitrogen toxicity - lockout

    Hiya I have a girl who is not doing terribly well. 2 things are apparent, there is some clawing at the end of the fan leaves, which suggests N toxicity. Also there is some yellowing between the veins which suggests a Mg deficiency. I just wondered are the 2 things connected, like if you have an...

    Magnesium deficiency?

    Hiya Having a real rough time with my 2 girls at the moment. This is an AK59 auto in dwc under a QB288 135w basic board. Temps and RH are ok i think. Shes been getting Canna A+B up to about 700ppm in the bucket but shes starting to look hungry. Had a look at some pics and Mg deficiency looked...

    Advanced deficiency help !!

    Hello to anyone still interesting in this carcrash grow :-D im not keeping track of times which probably isnt helping but anyhoo...from 5.8/500 to 6.1/400 so again evidence she is feeding which is good. But the damage/rusty spots seem to be slowly creeping onto new leaves. A while ago...

    Advanced deficiency help !!

    So after flushing the SD for 24 hours, i gave her 380ppm (my water is at 150 so thats really 230). That dropped to 280 in 24hrs, which at least shows shes absorbing the nutes. So i raised it again to 450. I just hope she can continue feeding but im really not sure shes gonna make it. This is the...

    Thanks for replies guys. WIll defninitely sonsider the foliar feed, can you do that with calmag? Heres the damage on the other plant the AK59 which i noticed this morning.

    Advanced deficiency help !!

    Wow thats amazing love my mountains, skiing in winter, hiking and mtb in summer, brilliant ways to keep fit and have fun! That last point has been noted. So the SD (the almost FUBAR one) has had 24 hours flush to hopefully deal with the nutelock and was given 250ppm hopefully she sucks up some...

    Advanced deficiency help !!

    Nice. Must be amazing up there, would love to visit with my skis one day! But im thinking how ive over fed my girl, its possible ive not been letting it drop enough, and/or bumping it up too much. Eg my other one the AK59, that has gone from 635 yesterday morning to 535 just now. Should i let it...

    Advanced deficiency help !!

    Thanks rkymtnman, will do as you say but im really not hopeful, she is well on the way to being FUBAR. Damn. Never lost a plant before...btw have often wondered about your name is it somehow derived from Rocky Mountain Man?

    Advanced deficiency help !!

    Correct. Guys I need a plan, I don't think I have much time. My dilemma is if it's a deficiency or lockout. I'm going with lockout as rkymtnman suggested. From what I've read the way to treat this is plain phd water for 48 hours then reintroduce nutes at low level. Is this the way? Thanks!

    You think that could be it, phosphorus deficiency?

    Advanced deficiency help !!

    Thanks. The ppm has been dropping regularly, not by much, but arent you supposed to work on the idea that if the ppm drops you can increase the ppm? Will look into how to treat nute lock, if it can be treated. Hi AH, i think youre referring to another thread, that was a different plant (AK59)...
