Why does Canna Terra Flores gives nitrogen toxicity to my plants every time?

[Markyb]

Hi! Am I doing something wrong or missing something?

I'm using Canna Terra line synthetic nutrients. Terra Vega(Vegetative) and Terra Flores(Bloom) The vegetative phase goes more or less well now, I ramp up the feed to around EC 1.0 and keep feeding that until the stretch is finished and I change to bloom nutrients. When I change to bloom nutrients I start with little lower concentration EC 0.8, and BOOM its nitrogen toxicity instantly, leaves go insanely dark and shiny. I dont see nutrient burns though.

I don't understand how it is possible to have nitrogen toxicity when the bloom nutrient has less nitrogen and I'm starting with lower concentration.

Am i understanding the EC feeding wrong? Everyone is saying 0.8 and even 1.0 is on a low side, but EC 0.8 bloom nutirents totally wrecks my plants.

I don't know your nutes but do you continue with your veg nutes while you add your Bloom nutes?

When I flip plants I continue with veg nutes all through my grow just tapering off after week 2 in flower at week 2 in flower I'm feeding max veg nutes and start bumping flower nutes.

My numbers in veg are 3 parts I start at 2/2/2 ml/gal them 3/3/3 - 4/4/4 - 5/5/5 - 6/6/6 at week 2 in flower then week 3. 4/4/8 - 3/3/8 - 3/3/8.

So you can see I build my nutes up then taper off into flower. I also add a bunch of other stuff but I don't want to confuse you.

Hi, thank you for your reply!
I used to do that in couple of my previous grows, slowly switching to bloom nutes but I always got bad P deficiency.
Canna terra Vega has 3-1-4 ratio and Canna Terra Flores 2-2-4

Hey lets square this way.
Canna terra has a grow schedule that you yourself makes up.

I did calculate with light feed and I'm nowhere near those suggested amounts. Light feed suggests 5-5.5mL/L and I have been feeding like 3mL/L at max..and still getting way too much nitrogen.

 

[JIMKSI64]

What is the pH ?
How much variance are you getting as the water level drops?
What specs did you put into it.
I put in a very generic balanced medium feed and by flower 1 it's very low, below 1.5 per
Remember it defaults to gallons

We don't have pics so I'm going by your description. You mentioned it's dark and shiny but if it's not clawing or burning it's probably a heavy load or an extremely efficient use of available nitrogen which is a good thing. You can probably lighten the feed even though it's a pretty modest strength -- again because it's using the nutes efficiently. Follow the feeding guidelines of what you're using but based on your own results, you know you can go a little lighter, at least for the flip load.

pic and where did it start how did the spread look

Hi @Ninjadogma and @amneziaHaze

I uploaded the pic, sorry I forgot to attach it in my original post. I took the pic with lights out so it looks maybe even darker than it actually is. It looks droopy like this after lights are out and it looks much perky during daytime. Just thought to mention that its not always this sad looking, only during night. And the weird thing is that the topmost leaves are the darkest and bottom level leaves look much much lighter even though it's not clear in the actual picture.

It started right after I moved to bloom nutrients. Like BOOM, one night and the leaves went this dark.

Bottom means hungry top means overfeed.
Dont see a problem in the photo can you zoom in

Gorgeous plant and what you're describing with the droop is normal transpiration. Not all plants do it but you might even catching it anticipating the lights coming on by perking up or dropping an hour in advance of lights on/off. That's cool to watch. Hope you don't mind, gonna submit this for "plant of the month."

Thank you :)
A small update, she is doing pretty well and looks like she is producing a decent yield for a zero-trained grow. A little bit of too much light on the upper leaves on the main cola I think, but there is not much I can do about it because the light is already ziptied as high as possible. Should I be worried or just let it run like this? I'm running the 100W light at 100%, but I'm worried if I dial the power down the lower leaves/buds won't be getting enought light. (I mean the mid level buds.. I know the very low level buds are definitely not going to get enough light) With my next grow I'm definitely going to start learning and applying some LST methods to get more even canopy. For now I have just been trying to get the hang of the very basics and not been worrying about the canopy level.

I also definitely starting to enjoy the grow process much more, rather than stressing out. :) The Autopot was a real game changer for me, even though I still have a lot to learn, now at least I don't have to constantly stress out about the watering.
And even though my yields or quality might not have been up to standards, I'm still kind of proud of that I have never ever bought or received weed, not even once. All the weed I have ever consumed has been self grown :)

Hey whats up @Markyb Your plant looks great man!!
If you think the light is damaging the tops of the colas, maybe turn it down just a little bit......like you mentioned, too little light getting to the middle or lower canopy will affect the yield.
