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.

Thanks dude. I'm using this tutorial by dr mj coco and the inflow EC is 1.0 and the run off is coming out at 0.8 EC so I'm guessing they are underfed? https://www.cocoforcannabis.com/managerunoffec/

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

I measured 'run off' when I was recirculating. Now that I have a substrate in the mix I find run off specious because you don't know the break down of the retained salt, just the EC. Also you just repotted so you don't know initial CEC charge.

Also I don't use your nutrients. I use GH Flora trio. It's all we had in '96. Anyway if you feel it's starving up your EC. Her response will give you your answer and then you'll know. I wish you the best on this.

Is your coco washed, rinsed, buffered, etc..? If so, pay attention what goes in. If it's not, do that, and then pay attention to what goes in. Imho

It's just canna coco professional straight out of the bag dude, I think it's already buffered but I'm not sure?

My new substrate! Although I guess '14 doesn't make it new LOL time flies. I love that stuff. These aren't seedlings but they are a couple off my recent table. Mostly Bros. Grimm genetics. I needed to burp jars so I snapped a pic for you:

That's in Canna Coco and GH Flora Trio with CaliMagic about 500 PPM

Those look lovely, I looked online for potassium deficiency and it looks similar to the first picture I posted, it almost looks like nute burn but it's not?ae167f604e64fb220459b6f38e8b4b93.png

Excess N, excess Ca and excess Mg block K, which would lead to a K deficit via lockout. You have 0.6 tap water. That is likely mostly Ca with some Mg along with a little N and whatever buffers are in your tap. Then you added .4 of Canna.

Like I said. Go with your gut and up your EC you will know which within 3-5 days. Only your plant has the answers. I know what I believe based on killing many plants over decades. The way you learn is to try. The plant will answer you. Go for it.

I just bought a brick of the canna coco up in Michigan. Looking forward to trying it out

The professional is pre chewed! I love that shit. Oh and he should listen to your taking his tap water out of the equation too. I've been crazy busy my garbage disposal died LOL

I know Dutch Pro do a Canna A & B for hard water which has less Ca and Mg in which I probably should have gone for instead of Canna A & B. I've always thought it could be a lockout because I burnt them up badly when they were seedlings which could have caused the lockout? But since the coco I was using at the start was precharged I was only giving them water for a week or two after I burnt them up until I saw signs of the potential potassium deficiency meaning the precharged nutrients has probably ran out? So I started feeding them Canna A & B and the potassium deficiency got slightly better for a while, but now when I test my run off EC it seems on the low side. I don't know whether that's due to adding Fresh canna Coco with no nutrients in which could have caused it to lower? But according to Dr Mj Coco the run off EC should be slightly higher than the inflow? I know my tap water has a lot of calcium in but that's about all I know. I'm leaning on the side that they have a deficiency because my other plants seem like they are light green which could possibly indicate that they are slightly underfed?

You aren't feeding enough.

Use the custom setting for your starting ec then select light feeding

I thought so, but I don't want to up the EC all in one go, I want to slightly raise it over the course of a week instead of raising the EC all in one go? Unless I'm fine with upping it from 1.0 EC to around 1.2 - 1.4 all in one go?

Like I said I rarely if ever measure run off. I don't find it useful. If that is what you believe from your research up your feed. Corey knows his shit as does TCH. You will know soon and I hope it works. Statistically it's overfeeding and from my old profession we went off the numbers we had. So try it and watch her. In the end that is what we all do. That is how all of us learn to grow. We try it with our plants and that teaches us.
