Toby Posted November 28, 2018 Share Posted November 28, 2018 Hi Guys, One of the strains is showing some leaf discolouration. Not sure if is N deficiency or toxicity? It has a dark blue line running through it and become lighter on the edges. Image below. All the other strains with similar soil and watering regiment are growing as they should. Please help and identify what the issue could be? Images attached. Plant in question on the left. Quote Link to comment Share on other sites More sharing options...
greenkush Posted November 28, 2018 Share Posted November 28, 2018 The plant on the left looks like its suffer from calcium/mg deficiency. Quote Link to comment Share on other sites More sharing options...
CG420za Posted November 28, 2018 Share Posted November 28, 2018 Maybe that strain is a heavier feeder than the other bru? Quote Link to comment Share on other sites More sharing options...

That's the thing Blue Dream is not heavy on nutes, based on pass grows. 39 minutes ago, greenkush said: The plant on the left looks like its suffer from calcium/mg deficiency. Ill give it some Calmag+ with the next watering and monitor. Thanks chaps Quote Link to comment Share on other sites More sharing options...
CG420za Posted November 28, 2018 Share Posted November 28, 2018 @Toby, i haven't used calmag since i'm growing in soil. I thought that was for use with synth nutes only. Just goes to show i'm still a noob Quote Link to comment Share on other sites More sharing options...

Just goes to show i'm still a noob I won't use it in my regiment only as a problem solver. Don't want to be killing off precious microbes. I'm a noob myself. The more you know, the more you realise how little you know. Quote Link to comment Share on other sites More sharing options...
CG420za Posted November 28, 2018 Share Posted November 28, 2018 Awe, that statement is so true. I've been adding epsom salts (1tsp to 4L) like once every 4 weeks and I haven't had issues. 2 Quote Link to comment Share on other sites More sharing options...
Green Leaf Organics Posted November 28, 2018 Share Posted November 28, 2018 Magnesium sulphate will only hurt you microbes in large doses . At the doses me use it's actually beneficial to use it . A lot of soil recipes actually put a cup of magnesium sulphate into the mix. yes that plant is suffering from MG def so magnesium sulphate would be better to use over calmag+ as you dont look like you need the extra calsium or nitrogen 3 Quote Link to comment Share on other sites More sharing options...
Toby Posted November 28, 2018 Author Share Posted November 28, 2018 Thanks gents Epson salts it is. Ill follow your recommendation @CG420za aweh 1 Quote Link to comment Share on other sites More sharing options...
Budwizer Posted December 5, 2018 Share Posted December 5, 2018 (edited) Foliar Epsom with Fulvic 5 grams Epsom to 1ltr, 3ml GTH Fulvic to 1 ltr. Spray the underside of the leaves. Do one ASAP, then again 3/4 days later. But what has caused this? What you’re seeing is a symptom. You need to get to the root of the real problem. If it’s a problem now, then it’s gonna be a problem through the whole grow. Mg def means one of two things: too much Ca or Na or P in the mix, or pH out of whack. You need to sort the problem, then the symptoms will go away. Edited December 5, 2018 by Budwizer 2 Quote Link to comment Share on other sites More sharing options...
Toby Posted December 6, 2018 Author Share Posted December 6, 2018 Thanks, @Budwizer, I fixed it with Epsom and AACT over the week. Bounced back beautifully. Shot gents. My soil mix was a bit too rich, so I broke it down with equal parts, coco, ewc, my soil mix & perlite. Didn't add lime for the extra coco. I think that particular strain was just more sensitive to the deficiency. IMO. Ill monitor and Epsom salts as per @CG420za schedule above. Pic below a week later. 5 Quote Link to comment Share on other sites More sharing options...
