Which deficiencie?

[Cringer]

Hi,

my 15 Day old Plant looking not so good it looks to me like a magnesium deficiencie? I see this 3 Days ago and give cal/mag 0.3 ec but she didn't look better today. Total EC I give 1.2

Good day Andi,

I don't think you would have deficiency with 1 or more EC feed at this early stage. My gut tells me that you have a pH lockout but we would need a lot more info to get to the bottom of that because they might just fill in darker on their own.

What is your soil medium? Is it coco all the way? Have you been pH your feed properly? How long ago did you start nutes? what kind of light are you using?

Ph lock I don't think that because i pH my Water every watering to 5.8-6.0.
I feeding after first leaf set 0.7 EC very low dosage my Tap has an ec of 0.4 but I Add to late cal/mag I think.

Medium is full Coco Canna professional pro! Lights are Cob led.

I had some grow so fast they do this. But they grow out of it quick. I wouldnt worry too much unless the leaves arent getting darker or its stalled

EC 1.4 to High? The Nutrients chart from Canna say 1.5-1.6 EC I think it is ok for a few watering when she is darker i decrease to 1.2

1.4 might be too high for this young of a plant,... symptoms are kind of generic, could be a few things,... including an off batch of coco (Na toxicity),.... Also, have you calibrated your pH meter recently? ..store it in the right solution? Don't let it dry out? They are easily knocked off calibration if not cared for properly,... a bad reading might be masking off pH in pot,....

I decrease the EC to 1.3 to High also? Ph pen calibrateted every 4 Weeks.. Normally I don't need a pH pen I now my Tap Water are Ph 7.0 and when i drop 2 drops of PH down to it in 0.5 Liter water the PH goes down to 6.0

good on the meter,...are you using Ca-Mg? In your ppm readings, how much of it is from water alone?

1.2 is too high IMO for sure. Looks like she is getting locked out. Flush it, and start over with quarter nutes at that age. Those recommendations are for photoperiod plants, not autos. Autos can survive on 450 at that age. Start her at like .5 max and see what happens. I bet she will like that.

To flush, just run 2 times he volume of your pot of phd water through the plant, then start over mixing a new batch of nutes.

It would also be interesting to find out what the EC of your ground water is, plus if you have a bunch of salt build up in your coco. Did you flush the coco before using? What brand is it?

0.4 is my Tap Water alone. I Add 0.3 to my Tap Water and 0.6 Base Nutes. Total EC 1.3 now

That's how she looks today
