It is canna coco a + b

You don't use cal/mag?

No, I use only this. Thought that a + b will be enough for that stage. What should I get it?

I had some experience with canna coco, and I always had to add cal-mag. Anyway what's more important is, 2ml/L is way too much for autos. I had some left over canna a and b, a diluted 2ml/l of each in litre of water and took PPM readings, and it's 655, this concentration must be at the middle of flowering stage, as I already said, autos are very sensitive to nutrients.
Just use 0.5 ml per litre of Canna a and b, 0.25ml/L plant magic magne-cal. Increase concentration of canna slowly, as you see progression, but keep cal/mag 0.25ml/L all the time.
Now you need to flush you plants with plain pH 5.8 water, until you collect same amount of run-off as your pot size than give them food as from my advice. Don't water too rapidly, and don't worry about over watering your plants in coco.

Oh dear dude. That's a lot for me to keep on. Will tap water be ok? Should I flush it now? My pots are 11L so that amount of run off..are you sure?

Yes I am sure, flush them now,after that flush don't water them for 3 days, and than start daily watering scheduled(one day water one day food).I believe you have not used flushing agent for coco to clean all salts from it before potting your plants in it. If you want to avoid all this pain, you need to switch to soil, coco really designed for self watering pots and irrigation systems, it meant to speed up growth and increase yield, unless you are growing for business, you have no need for coco or any other hydroponic medium, soil will do good enough for personal use.

I am doing for myself only. Just my friend used coco so I went for it and want to stay with it the same like I wanna stay with CFL's. On other side I have no water ready ( tap water been poured in the morning) to do the flush today and I can't collect around 20L as you said to equal to pot size. I will have only 4L

Why do you need to prepare water, why not straight from tap. If you can drink your tap water, you can give it to your plants. Just buy TDS meter from ebay for around 10 baks and you will know exactly what's in your tap water, and how hot your run-off

I would flush as soon as possible, but if you leave it till tomorrow it should not do any irreversible damage.

Flushed them this morning with 11L of tap water. I ordered magne cal as well. One plant has more dark spots. Poor girls.

that's good, from tomorrow start giving it 0.5ml/L of canna a and b, as soon as you get cal/mag start adding to your feed at 0.25ml/L. For a week feed it once a day. Than do one day feed, one day plain water and don't forget to keep the pH at 5.8, for pH down use phosphoric or nitric acid, for pH up use potassium silicate(liquid silicone), DON'T use citric or acetic acid (lemon juce or vinegar) for pH down, And no hydroxides or carbonates for pH up. And most important, let your plants grow, don't disturb them by opening your tent every 15 minutes to check them out. Open your tent only when you need to water them and take a picture to see progression.

Order TDS meter as well, they are very inexpensive.

Isn't to early to give them a water? They just been flushed so coco is very moist. Will I not overwater it? Water till the run off? Thanks

The way coco works is different to soil.
Here's official canna website, they provide full info on how to use coco http://www.canna-uk.com/using_canna_coco
Read this and you will understand what I mean, they explain it way better.
There is another method, when growers follow next schedule, day 1 feed, day 2 plain water, day 3 no water, no feed to let them dry out. I never tried this way, you can try both ways as you have 2 plants and see the difference at the end.

Those are Autos, I would've waited 2 weeks only light water..no nutes week 3 light nutes Bloom nutes. .autos are in baby stage week ..like a human baby you wouldn't feed the infant food.they get a bottle of a light mixture for size..as they get older..add more cereal aka nutes..light buildup

Hi Johny, Not much better. Still some yellow and brown spots and not much of grow. Left bottom leaf of plant on the left is affected the most. I gave them today some nutes and tomorrow water. Ordered tds meter and waiting for magne cal sometime this week.
