What the ****

Even as a water guy i loved coco just hated it at the same time .

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.

I started out using soil a couple years ago with good results. I switched to coco trying to get the big yields but just has Not giving me that. I never check the e.c only and every now and again ppm. But I'm about to give them a good flush now

There is a big clue... water that has been sitting out for a day will be depleted of o2.
Unless you got a bubble in it.

Anyway o2 depleted water will cause big problems....

So will that salt build up.

I was having problems when it was coming out the tap. I recently bought and before I had well water that came threw a softener so I had to buy all my water from the store which was ro water. When I moved same strain same lights same tent just at a different house with city water I started using city water right from the tap and it caused alot of issues. I started letting the water sit for 24 hours to help chlorine evaporate and things changed for the better. However these are new strains though.

I'd blame the Coco, some may like it, but I used a mainly Coco mix and found it fickle.

Well if it sits for too long you really need to oxygenate the water. All you really have to do is pour it between buckets a few times

Id say a ph or root problem. Either way there not getting the nutes they require. When you water at 5.9 do you let 20-30% run off. thats important to remove the salts. Second what is the ph of the run off. I was growing in coco, feeding at 5.9 and never checked ph run off. Then had plant problems that looked like TMV. I checked the run off it was 5.3. I started watering at 6.5 and the problem eventually fixed it self. PH is the most common source of lockout. I also found silica was helpful in preventing a ph plummet.
If its root rot then make a tea or use hydroguard/ aquashield or whatever beanie product you prefer.

On a side note I have been trying coco and to be honest its been a difficult process. DWC or drip rock wool was easy peasy in comparison. Also, I have never ran into a fungus gnat until coco. Now their a plague that I'm only just getting under control.

My light is a 1600w mars 2 and it seems to work great. I don't know why people shit on these things. Fruitiest smelling buds I have ever grown. Why don't you use it in flower?

This is true and yet not entirely bear with me cause im not a scientist.

Firstly its untrue cause youd be hard pressed to tell my mom whos growing plants that sit in vases till the water is gone

Disolved oxygen levels are usually not the problem.

More proof can be found in the kratky method

The problem is getting water that contains the DO. To flow through a mass of roots.

Just my 2 not saying you are wrong or anything like that

Except that... You are.
Lol
But thats okay. I don't mind being wrong.

I'd like to point out one thing though and that is that how long do flowers last in a vase?

Are plants in vases usually already cut like a bunch of flowers for example?

Tap water that has sat out for a day or 2. But yea I know about calmag just never had to worry this early in veg I always waited til about a week before flip to start calmag

Coco needs calmag from start.

i've started using pro-mix now, but grew in coco for a long time, and 5.9 is going to cause you Mag problems, which is what it looks like is at least partially wrong. center your ph at 6.1 in coco or you're going to have problems. people can tell you its hydro all day, but it's not, it's a hybrid, and you have to treat it that way or you'll have problems.

canna coco should be precharged, i'm not positive about that, but it's one of the better brands, i'd be highly surprised if it wasn't, so you may need some extra cal-mag, but it shouldn't be that bad.

We have house plants that live for years in the vases lol but its not a plant with a 5 gallon root ball either

My post was merely an example anyone can see
Not saying my mom flowers weed in a vase though I wish she did lol

Just saying that people get all worked up about DO. When they normally have plenty

Getting it to the roots is another story.

I dont think setting your water overnight will hurt the DO lvl too much to worry about..

But you are correct in saying that swishing it between 2 buckets will help...... but how much? i would want to see DO meter readings .

Like i said dont wana take the thread off course just trying to add to it
And im wrong all the time lol

Put in soil she seemed to have had a turn around cut clones off her and threw into flower room
