Plants aren't doing good.

I am treating it like soil. I let it dry out and then feed them with about 1 liter of feed at an E.C of 1.5 (20ml of canna A and 20ml of canna B per 10 liters of water) And some rhizotonic to help promote root growth? They are in 10 liter plants pots now. I transplanted them about 1 week ago. I just sit there with a 60ml syringe lol :bigjoint:
You should not be allowing coco to “dry out” by its very nature the drier it becomes the more the CEC fucks up.

it pretty much needs to be saturated all the time without being water logged.

If you chose coco to use it like soil then you’ve been guided down the wrong path.

Don’t feel bad I was using it wrong for a while too and only feeding once a day when I was hand watering and they were drying out between the feeds.

My best grows have come since I switched to automated feeding (I know this isn’t possible for a lot of people).

my tap ph is 7.4 with a lot of calcium in the water (alkaline) and dtw coco actually works out perfect with this type of water. Take your water, add nutrients, and adjust down to 5.8, then feed. Even if the PH creeps back up once it's in the soil, if you are feeding at least twice per day, you are giving your roots enough contact with that lower PH feed for them to take up nutrients. The key point here is you need to feed at least twice per day, once your roots have filled out their pot...so, during all of flower for ex. Some people feed more than that, but it's a PITA if you are hand watering, so twice is fine.
if you use masterblend you will have have a 3 part nute and calcium goes on it own soo you can control amounts. its a powder nutrient as for ph i use ph- from general hydroponic allsoo powder form.it doesnt have end date it will last you forever. if you buy a bigger package like i did 1,5kg for40 euros i did 6 grows i cant really tell levels reduced a lot, i have 1 plant 10L pot.i would recommend to buy one of those fency scales that go to 9.001g they are 20 euros on amazon

maybe ryzo is making some problems. when i get lots of bacteria ph is allways 6.4 that could maybe help somehowe...

Should I give her a feed then because she's drooping like a bitch. The coco is still slightly moist but she is drooping a lot compared to the rest. The new growth is coming through green but the rest is yellow underneath
Plenty of info is available on coco
But to summarize
Feed to runoff
Always use nutrients not plain water
And don’t allow coco to dry even if it means watering multiple times a day
And never let runoff soak back into pot
It’s a lot of work but coco like hydro has more explosive growth than soil

I had a running problem with my indoor grow for a couple years, when I moved into a house on city water.
As an experienced grower, I could not figure out the problems I was having.
To make a long story short, it was the Chloramines in my water destroying my root zone.
My carbon filter was only removing the Chlorine, not the Chloramines which cause the Chlorine.
I had to buy a 5 stage reverse osmosis system to remove the Chloramines.
Uses two different sorts of carbon filters.
Now, my water is stabile and doesn't creep back up after adjustment, and no root damage from Chloramines.

this quote is the bare minimum for coco
if you cant handle doing all of that then you can go to dwc its a lot less demanding you just need to buy an airpump
