Unhappy looking

got some plants here which are youngish, been in these small pots for about two weeks now. They aren’t looking good at all and can’t be sure as to why. I’m thinking the yellow leaves are hunger rather than anything else?
They was getting 1ml of canna coco a&b per litre. EC pen broke and then local shop was shut. Have ordered one online and it arrives Saturday. as I thought it was hunger I upped the feed to 1.4ml per litre. When the new pen arrives I will work out what they been getting with that and go from there.

Not seeing much in terms of side branches wanting to start growing either tbh. Was thinking just to go one pot size up and stick them in half litre pots when the new ec pen arrives. Along with some rhizo which I’ve ordered. Be certain then they’ve got bit more room and getting the correct feed. Tbh the roots aren’t even looking great. Not been letting the coco dry out but yeah roots IMO should be looking better.

Anyway let me know what you guys think, fingers crossed it’s just a bit of hunger and will improve with the correct feed and into slightly bigger pots.

Hungry. Are you feeding daily?

thanks for the reply, I was thinking similar. I’m feeding them soon as the top of the coco starts to look dry. Working out about every other day at the moment.
The roots aren’t the best looking either tbh. Actually n this is just me being picky. It feels a little like the coco in these pots has some how ended up bit pressed than I like it. Is why I was thinking be good to pot up into just the next size pots n have the coco more loose and fluffy feeling. Still would only be small half litre pots and with the correct amount of feed.

I suppose not having a ec pen I decided to be extra cautious. my new pen arrives Saturday so then I will work out what it is they’ve been getting all this time. I thought it was just hunger but didn’t want to bump things up to much as in the past I’ve done that n ended up with clawing.

fingers crossed then they should start to pick up.

You cannot over water (feed) in coco with plants that size. Personally, I would feed those small pots 2x a day.
Fed more often is better than raising EC. Point being to maintain the nute levels in your coco.

I always get to the point where watering daily. Just thought best to let it dry slightly at this stage when they are young. Still watering every other day like I say. I ain’t gonna bump the feed anything to him as had clawing in the past. Will probably decide based on when I see what I have been giving and what it works out as.

In the past have been guilty of being stupid with coco I have to be honest. Dont laugh lol… I was pressing the coco down when potting up. God knows why but it ruined the whole benefit of growing in coco. A mate would see it and tell me the pots feel light and I’d water and they’d be over watered. Was an off chance he gave me a cutting and I potted it up and noticed his coco felt a lot more loose and fluffy like.

Anyway glad it appears these are just hungry. Been a little stressed thinking it’s gonna end up being something else. Roll on Saturday when I get the new ec pen.


edited to add;; gonna go with your advice as well and keep the feed in Range and feed daily. Rather than increasing the ec as like I say I have experienced clawing when I’ve done that in the past.

Most certainly hungry. Need some N

How many feeds you think it will take to see some improvement? the tops are darker of course but yeah want to stop the hunger rising.

Slightly bigger pots and correct feed come Saturday. I was giving them 1ml then went to 1.4 but just gave 1.5ml canna coco a and b. My mate has said his plants are getting that and a week behind mine but look fine. Suppose he has been feeding that amount longer than I have though. He also has an ec pen and says it equals a feed of 0.6ec. Anyway just be better when my pen arrives and can work things out.

should be a minor problem to fix right? hate seeing them looking so horrible lol want them to hurry up and get going whilst looking good. Hopefully find a mum in this lot.

I would think based on how young they are you’d be fine to just feed again as you have been. Early veg growth generally in the ballpark of 1-1.5 ec. Ive generally followed water, water, feed. If you need an adjustment you can feed once more instead of a water. Give them a few days minimum to notice any changes. Don’t go upping your nute levels to try and get a faster result, just substitute a watering with a feed.

Sorry just read you’re actually using coco, you can just keep up your daily feed at 1.5ish

Overwater and not enough nitrogen, looks like problem got fixed though

that was 1.5ml of canna coco nutes lol not 1.5ec, that IMO would be to high for plants in veg. My ec pen arrives tomorrow but a mate says that’s seen his water increase by 0.6ec. The thing is I have jumped up before and run into clawing so I will onlyincrease things very slowly if that’s the case

overwater? You know I’m in coco right and even then been watering every other day. It’s hunger though glad everyones agreed on that. makes my life a lot easier lol. will see what they’ve been getting when my ec meter arrives and make the adjustments from there. Cheers

No doubt on the hunger. Slow and steady increases on nutes as roots develop and new growth occurs. Things will shape up within a week. Small adjustments and you’ll be just fine. The lower most leaves may have been sucked dry of nitrogen too far, so likely won’t see them green up again.

Cheers, yeah the newer growth is looking a much better shade of green. Just know though that the hunger starts from the bottom so don’t want them getting hungry as well. ec meter tomorrow will tell me what they’ve been getting. Will see from there what to adjust by.
I am going to also pot them up inside slightly bigger pots, either half litre size or 2litres pots. Got some rhizo arriving tomorrow as well to help the roots out.

Like I say previously I was pushing the coco down to much when potting up. would take longer to dry out and any time I’d water them unless bone dry they’d look over watered. Now treating the coco like coco I feel better about getting the roots going and seeing faster growth.

Perfect, a nice pot up with more fluffy coco, and you’re going to take off like a rocket

fingers crossed man haha. I’m confident as it is just a hunger issue. Will do an update tomorrow when the ec meter arrives anyway as can be sure then what they are getting.

Also gonna write it down what adding 1ml of the feed does to the ec. Just so I can keep it for the future. I gotta be honest I didn’t use an ec meter for ages and done fine just reading the plants. Then I was bit to keen with the mutes and got some clawing and looks to have made me start being to cautious lol . Sure the last time I saw the clawing was when I went above 1.6ml per litre. Leaves at the top now look a nice shade of green tbh with 1.5ml. Be good to see some new growth in a bigger pot and the lower yellow leaves die off so can truly see how the plants are doing.

anyway lesson learnt and plants will pull through.

Okay pen has arrived. adding 1.5ml which they have got twice works out at an ec of 0.8. Now the top of the plants look a decent shade of green. The lower leaves which have turned yellow I doubt will come back.

Just concerned if 0.8 is enough? Don’t want that hunger continuing to spread up the plants. The tops of plants n new growth though all looks a good shade of green to me. And probably better to under feed slightly rather than over feed right? So thinking pot up and the 0.8ec. And see how they do with that.

Right this really is just for anyone using canna coco nutes and has broken a pen but knows their background. it seems the ml you add per water increases the ec by half of what you’ve added.

1ml a and b into a litre sees an increase of 0.5ec
1.2ml into a litre 0.6ec
1.4ml 0.7ec and so on

makes life easy I suppose lol. will post a photo soon enough and hopefully they are looking better.

I use 4ml a&b per 1l
