Urgent help needed

What is wrong with this plant? It's been treated the same as my other ones and the other ones are fine, I am growing in coco, The PH is 6.0, the E.C is 1.0, Temps are around 27c, The humidity is around 50% - 60%. It looks like nutrient burn but it's not because the EC is only 1.0 and they are nearly 4 weeks old.

Might need a higher EC, it looks like it's starving for potassium mostly

Thanks dude I will up my feed to 1.2 EC next time I feed them

Might benefit from a little boost of nitrogen to promote some more growth looks like its consuming itself

Thanks for the help dude, I'm definitely feeding them on the lighter side, because I burnt them up to start with. I'm going to up the feed next time I feed them

What nutes are you using and your just hand feeding yeah??

Nitrogen is very important in the seedling stages to promote new healthy green growth did you start it in that pot or transplant recently??

I'm using Canna A & B dude. And yeah I'm just hand feeding with a run off system.

I transplanted it recently, about 2 days ago, but it looked like that before transplant

Looks like nutrient burn to me and if you look at the faint tip yellowing on the new growth looks like it's continuing. At that age I'm feeding mine about 0.3 to 0.5ish. I'd back off some but it's your plant. Either way you'll know soon. Best of luck with this.

OK did you by any chance cause any root damage ya see when a plant is already in deficiency mode even the slightest little bit more of added stress cause be enough to push it over the edge I'll send you a pic now of plant that are only 6 days from sprouting so something bad is stunting that plant I would back off everything nutes wise except for something that is good for promoting root development depending on what your feeding and some nitrogen, make your next watering halfbthe amount you normally would and just plain ph water between 5.8-6.2 and then the watering after I would go just something for the roots and nitrogen, how did your root look when you were transplanting snow White and hairy looking or were they a little brown or yellow??

My tap water is hard water. It's 0.6 EC so I'm only feeding at 0.4 EC. It's definitely not nute burn. I think the plant is eating it's self. I have another plant that has been treated exactly the same with no nute burn that looks slightly underfed? What do you reckon? It's drooping after transplant also.

That's 6 days but I suppose I'm directing straight co2 into those propagator lids to try get them to make more use of there light early on. So like I said of it we're me I would plain water with half the amount you normally use for a little bit of a flush I guess and then start with nitrogen and a good root promoter if possible but that's just me it's totally your choice and I really hope you get it sorted bro any more questions don't hesitate

When I transplanted the roots looked pure white, I never damaged any roots, it looked exactly the same before transplant and I'm only feeding at 0.4 EC as my tap water is hard water at 0.6 EC

Thanks man, I don't know what to do at this point, I was definitely thinking about hitting them with some rhizotonic to help promote root growth and help them with any stress they are under. I think the plant is affectively eating it's self due to low EC?

Even to me that new picture is showing me an insufficient amount of nitrogen ya see they are starting to go pale green should be slightly darker but them if you go too much on the nitrogen you will get really dark leaves and it's nitrogen toxicity then either too much or too little will have a direct impact on leaf colour and growth if you watch your plant carefully try to learn by reading your leaves they will 9 times out of 10 tell you what they are looking for because you can't always see the roots most plant problems amd deficiencys will show a tell tale sign using the leaves

That's what I'm thinking dude, they are slightly underfed and need more nutes? Picture 1 looks burned but it looks slightly different to nute burn to me and it's probably eating it's self due to being underfed?

Something to keep in mind is that if your tap water is .6ec and you are adding .4ec of nutes, you are feeding them 1.0ec, not .4ec. You only know exactly what .4ec of that feed is. The other .6 is just whatever is in your tap water. If they don't respond well to straight tap water at .6ec, you may try out some purified drinking water and mix that up with your nutes and see what that gets you.

Rhizotonic is what I use I'm on the canna line myself and don't forget rhizotonic can be used as a foliar application aswel as top feeding go onto canna nutrient calculator on Google enter your desired tank size in your case you don't have a tank because your hand feeding so set that to 1 ltr and it will calculate exactly what's needed for 1ltr and then if foliar spraying just use half that amount today added to plain water or water with a little canna terra vega go the full strenght recommend for a lot on the vega it will be a good boost of nitrogen, but don't foliar spray the canna terra vega just top feed that by itself the reason I'm recommending to foliar spray with rhizotonic it will help to heal the leaves that little bit quicker because it's not relying on the roots to deliver it too the leaves cuts the time a little bit down so leave for 2 days and watch it see if it starts to improve do canna terra vega top feed and rhizotonic foliar feed of possible little spray bottle and give the whole plant a few sprays try to do the foliar feed just before lights out that why you won't get any hotspots on the leaves from the light through the water drops and give it more time to fully soak in naturally without the light drying it out too fast

My tap water is about 0.3 and I don't add nutes until I see yellowing. Then I start about .3 which makes a total of about 0.6 ish but it depends on the strain and how hard I'm pushing them. Like I said you'll know soon. There's a lot better growers here than I. Maybe @MickFoster can chime in with his ideas.
