    Can any experienced grower identify which deficiency this is?

    I calibrate my PH pen before every single feed/water so i'm almost certain that's not the issue.

    Can any experienced grower identify which deficiency this is?

    The rest of the plants are really healthy looking. Some of the healthiest I've grown tbh. It's just this one particular plant that's affected and even then it's less than 5% of its leaves that are affected. I'm just trying to catch it early before it gets any worse. This particular plant is also...

    Can any experienced grower identify which deficiency this is?

    I doubt it's heat stress since the leaves at the top (and closest to the lights) are unaffected. It's the lower-middle leaves that are showing signs of the problem. We'll see how the epsom salts work out and then go from there. No more neem oil for now. How often would you recommend spraying...

    Can any experienced grower identify which deficiency this is?

    I didn't see any bugs but spotted what could possibly be bug damage. There are a few small holes in the leaves. I know a lot of growers do a neem oil spray every grow just as a preventative measure whether they see bugs or not... so I figured it wouldn't do any harm just to be safe. But maybe...

    Can any experienced grower identify which deficiency this is?

    Thanks elkamino. I've got some epsom salts arriving tomorrow for the foliar spray. Couple of questions though. How much epsom salts should I add to a litre of water when I'm doing this foliar spray? And also, I'm due to do a neem oil spray tomorrow... should i do the epsom salts before or after...

    Can any experienced grower identify which deficiency this is?

    Thanks guys. Well the bug treatment started 2 days ago and they're due to get another spray down tomorrow. So any bugs that are causing problems should be dealt with by the end of the week. As for the interveinal fading it might very well be mag deficiency. These girls are Critical Kush... they...

    Can any experienced grower identify which deficiency this is?

    I use tap water but where I live has very clean and drinkable tap water.... less than 50 ppm from the tap. I'm growing in soil. Yes I have a PH meter and I PH the water and nutrient solutions down to around 6.3-6.4. This is the only plant in the tent that's showing this problem and they all get...

    Can any experienced grower identify which deficiency this is?

    Apologies for the less than perfect photos guys. This is the best I can do. I've started treating the plants with neem oil in the past few days so if it's bugs hopefully that will sort it. But I just think there is a chance this is some kind of deficiency. Do these 2 new photos give you any...

    Can any experienced grower identify which deficiency this is?

    These little yellow lines have appeared on several leaves of this plant. Looks like a deficiency of some sort and I'm hoping someone will be able to identify which deficiency.

    Plant showing signs of both underfeeding AND overfeeding.

    lol You're right, I do worry too much about them. All part of the learning process. But do you think giving them a few sprays with the neem oil could be detrimental? I was thinking to do it just in case.

    Anything other than bugs leaving this shiny/silvery residue?

    Hey guys n girls. I've noticed something today you might be able to help me with. I see some shiny residue on some of the leaves which has the look of thrips about it. I'll start with the neem oil when the lights are about to go out today. The only thing is I've been all over the plant and...

    Plant showing signs of both underfeeding AND overfeeding.

    Thanks for the advice guys. The plants got straight water last night and they seem to be loving it. Although I've noticed something today you might be able to help me with. I see some shiny residue on some of the leaves which has the look of thrips about it. I'll start with the neem oil when the...

    Plant showing signs of both underfeeding AND overfeeding.

    It's just gonna be water for the next week or so then. Although I was thinking of throwing some cal-mag in there but now I'm not sure if I should. The magna-cal+ I use from Plant Magic has an N of 2... do you reckon I should forget about using it for now?

    Plant showing signs of both underfeeding AND overfeeding.

    Hey guys. Here's a few photos of what I'm talking about. You can see the downward curl in the first 2 and I tried to get a close up of the tips too. You can see the slight yellowing there. As far as the plant being dark green... I'd say it's just slightly darker green than what I would consider...

    Plant showing signs of both underfeeding AND overfeeding.

    Thanks Indacouch. I better rein in the ppm's once i get back to feeding them in a week or 2. These critical kush have gave me a monster yield in the past but they've also proven to be temperamental little buggers at times too.

    Plant showing signs of both underfeeding AND overfeeding.

    Thanks for the reply :) I'll try to get some photos tomorrow, the plants are in their dark period right now. I've been PH'ing at 6.3-6.4 in soil.

    Plant showing signs of both underfeeding AND overfeeding.

    Some of the older fan leaves on my plant are showing classic overfeeding signs with the tips curling down. This has been the case since I last fed them around 5-6 days ago. My plan had been to let them dry out properly and then give them only water for the next week or 2. But as the day...

    How long can you expect to wait for new growth to resume after final transplant? Been 5 days now.

    Hopefully the roots are just trying to re-establish themselves in the new surroundings, like you said Spurdy. On the face of it the plants look great. Still nice and green and relatively perky. They have slightly bushed out in these 5 days since transplant but it's the new growth at the top...
