Coco problems

[haschblume]

Hello people

I need your help

I build on Coco (canna Professional) fertilizer is T.A Coco

My water I mix osmosis and line to EC 0.4 Cal/mg are optimal

I always have problems on coco the first few weeks, I'm not sure if I'm fertilizing too little or if I'm wrong.

I let the steaks root then in 0.2 l pots coco and then in I think 1.5 l 2/3 coco 1/3 perlite

I fertilized with EC1.0, in the 1.5 liter pot then EC1.2-1.3 are about two weeks,

I don't water every day but by weight, every 2-3 days,

I poured them over the first few days in the 1.5l pot, I think at least I poured it once every day at the beginning.

There is definitely something wrong!

I hope someone can help me

Thank you

Edit: it is a Pinneapple Fruz from Herbal

PH is the NL is so at 6

Increase your nutrient level! Nitrogen my friend. They are yellowing from bottom.Also repot them into bigger pots(root bound maybe).And start to water frequently,everyday to little runoff. Only at the beginning you can dry it some to increase root growth,after repot water every day.Also PH should be at 5.8

Yep...more nitrogen and ph levels between 5.8 and 6.1.

Also I'd water more regular..even if it turns into run-off.
It'll keep the Coco evenly moist and wash out any salt which might want to hang around in the substrate

I get that, that you want to water less in the first days. But once the small pot is full of roots,they can take it much better and really thrive if you give nutes more often

It might be cold. Keeping them wet a bit too long.

Big leaves, slightly droopy, with N issues. It all leans that way. So lets look at temps, before increasing the feed. Though that increase may indeed be needed, once we know the temp is right.

Im with Ca: it may be an issue outside of nute levels.
Are you growing with leds by any chance? Then you need to dial in environment properly. You likely need more heat to cause the transpiration that drives nute intake. Led light does not heat the cannopy like other lights do and means the environment nneds to be a bit hoter; +25C is what i would recommend but really its more about looking at the leaves: if they stretch out it means the plant is drawing water. No point in doing too much nute adjustment until then cause it just means youll have to redo your nute levels when you get the plant transpiring properly. The plant can live on more of a weaker juice or less of a stronger juice but always best for it to get correct nutrients thru healthy drinking.
Another issue is Coco buffering: coco has a way to hang on to nutes in the media. We solve this by doing one complete drench of high nute solution right after every transplant to make sure the coco isnt 'hungry' for nutes.
Second thing id rec is to measure ec/ph out every time you water to see what the roots are actually experiencing instead of just measure output.

Hy Temp is mind.22 -26 °C
I told them yesterday EC 2.0 .
12 hours latter she looks good
tonight I give them 1,8
I think I under fertilized
and yes its LED Sanlight s4
I try to turn the temperature up a few degrees.
thank you for helping

Ec 1.0 sounded too low for the size plants he has.
I sometimes give a freshly rooted clone more if it's a hungry one

It all depends on whats in the pot, thats why i always rec checking run off every time you water unless youre multiwatering everyday
