Very hard to trouble shoot with the burple light on. Maybe take some pictures with a white light, you got issues for sure.

The blurple makes it hard to identify what’s wrong with your lady. Take a pic with the lights off and you may get answers.

My guess is that it is locked out of or lacking phosphorus. You PH'ing your water ? A PH above 6.1 will lock out K ( posphorus) in a hydroponic medium.

Yes ph is 5.9.
Not sure if it was possibly the coco that did it. It sat in the bag rolled up for like 2 months it was dry as it was left over from before.
But I've only fed them with canna coco A and B

Its not thilled with its life but the new growth doesnt look too bad, nothing you can do about the older growth except wait for it to fall off. Thats the problem with coco, theres no forgivness. In soil there is a lot of forgivness

If its not ph or lock out
Id say magnisium.
Could be phoserus but i thought the veins would purple up the leaves if that was it.
Im not a horticultural master lol

No exp with canna though so im unsure if you need to add any additional magnisium cause i thought it was supposed to be a complete nutrient.

Was the coco reused? If so might have salt build up flush with ph water 3 times the amount of coco.(if thats the case)

Hope this helps

No coco was not reused. It was left over from a open bag I had from over 2 months ago.

Is the white stuff on the outside of your cloth pot salt build up?
I tried coco once and quickly decided I would stick with soil
Wish I could be of more help.
Cheers :)

It's a old pot. Could be but I don't think so I gave the pots a good rinse before I planted in them but once it dried it was back. I have been trying coco for about a year and about ready to go back to soil my self

My exp with coco did fine with ph 5.8 -6.3

Im sure you know coco uses more cal mag if i remember right then other mediums. .

Thats why coco formulas where made if im not mistaken.

I water every other day with 4 ml canna a and canna band between the 2 clones I have each take about 1/4th gallon

That doesn't tell me much about how strong of an EC your running.
But to save time.
Water until you have lots of run off
Don't let them dry out completely
Use about 2/3rds of the recommended dosage from the canna grow chart.
Use calmag on new coco.
Don't give up so easily. Coco is a great medium.
Soil may be "forgiving" but it like any other growing medium takes time to learn the ropes.

Edit, I asked about the tap water because canna products are designed to be ran with tap. Tends to be better than RO.

Salt build up is one of the worst things a grower can have, as long as you water regular and lots with good run off at correct PH it can be avoided. Don't let your pots reabsorb the run off either.
