plant size vs amount of nutes

Mobileaudio25 said:

Just starting my first go at coco. Using the canna lineup. Hand water coco sog table.

I see a lot of talk about finishing flowering around 800 ppm . If I am growing sog style should I be finising my 1-2ft single cola plants somewhere around there as well or does plant size have more to do with the amount of nutes I should be feeding?

I do trees in coco, and I also do SOG with coco here and there.
Both ways, I flower at 1.5 -1.7 EC.
Water with nutes every time, until roughly 20% run-off, and it ALWAYS works killer, no matter size of plants. I grow lots and
Lots of different strains also
You can(i do) lower the EC the last couple weeks, and save some $$ on nutes.
I usually finish somewhere around an EC of 1.0, trees or small ones alike.

IMO, treating smaller plants, in smaller pots, more like hydro, kicks ass better than hand watering small plants/pots.

Under a 1000w, in a 4X4 tray:
16 plants in 1 gallon mesh bottom pots, fed via basket drip stakes, 3-4 times a light cycle, is so fucking bad-ass!
I hand water 5 or 7 gallon pots when growing trees though.

Thanks for clearing a lot of that up. Do you prefer using ec over ppm? I know they can be converted but my ppm meter doesn't measure ec.

So are you running a flood table with top drip? Big resivoir with a water pump? I've read about this method and have everything to do it almost. You think its a lot easier on watering? Planning on doing a 40 plant sog 2 600w cool tube lights.

I choose to talk about nutrient strength through EC. There's different conversions to ppm's, it can confuse people. Find out what conversion factor your meter uses and check this chart:

Yes on the flood table with top drip. Well, basket
Drip stakes
I'm telling you, it kicks ass dude. I've grown practically every way out there, and it's my favorite these days
It's actually how I started with coco, the day coco hit
The stores. And it had actually pushed me to grow ALMOST exclusively that way for years.
But, IMO, it's too many plants when you have lots of lights

What's the easiest way to figure out which conversion factor my meter uses? I'm using :
HM Digital TDS-EZ Water Quality TDS Tester
What ppm/ec do you start out feeding your clones going straight into flowering? Around 150? Thanks for the good info!

I looked your model up, and it uses the .5 conversion
I personally, usually, feed my rooted cuts the first watering at/around .4 EC
That would be 200ppm on your meter. All of my meters use the .7 conversion. It is 280ppm on my meters.
I only water that low once or twice, and then i'm pumping them up gradually, over the next 3-4 weeks to 1.5 - 1.7 EC
