Nitrogen toxicity????

[Nicholls93]

so I’ve noticed one of my plants looks like it’s got nitrogen toxicity.. I’m using canna coco a+b and calmag I’ve stopped giving calmag was giving 2ml in 3 litres of water but she still isn’t going lighter, can I use less of the a to lower the nitrogen even more? or does a+b have to be the same ratio? I’m week 2 into flower my ppm I’m putting in is around 1000-1100

Are you feeding according to the nutrient manufacturer's recommendations exactly?

After week 2-3 of flower, the plants require far less N than in veg. Your nutrient label should show mixture amounts for veg and flower. Most often, manufacturers recommend way too much product (they do exist to make money after all), so mixing at their levels is almost always too much.

When I used GH Flora, I very rarely had to mix higher than 2/3 of what they recommended.

I’m using 6ml and they recommend 10ml can’t get my head around it, should i do a little flush?

i would flush a few times before feeding they look healthy and beyond green so some flushing will only do it good

Run a couple gallons of ph water through slowly.
Have you checked your run off it’s probably crazy high.

Looks like you could use a whole hell of a lot more light.

Dark green shiny leaves is a pretty clear sign of too much nitrogen but it looks like you caught it before it got really bad and started clawing.

Yeah it’s always 100-200 higher gonna give her a flush then

Yeah I’m now saving up for a new light definitely one of my problems

A slow flush. Like you’re making love to it. It really may be good with just plain water for a few waterings. May not even need to flush.

100-200 higher is nothing to worry about in regards to the run off ppms.

Your main problem imo is that your feeding it 1100 ppms when you should be about 600-700 for week 2 of flower. so yeah flush it out renute at a lower ppm and add back the microbe population you're flushing out.
