Grow Mediums GWK, 8.5L Coco Autopot with Airdome, MegaCrop Nutes

[Roasty McToasty]

Day 14ish update,
Mixed up a gallon with 4g MC, 2g CMP, and 1g SC. My ppm's were at 861 (ec 1.7) so I diluted to 720 (ec 1.4). Using a cheapo ppm meter so idk if it's right. They've greened up a little, hind sight I probably should've not diluted.

Once I work my way through my current supply I’m going to give this MegaCrop a try. I have a free sample on the way now.

Nice, its pretty cheap compared to AN and other nute lines. Seen some nice grows with it. I've heard that their Sweet Candy @ 1g throughout, will help with the terps and resin production. And of course their cal mag is usually necessary for us cob heads. @slowandeasy is doing a bunch of comparison grows over in the Mephisto section, and his threads are chuck full of great info, I'm just following his lead with it.

I'm glad you got me to this Roasty! I say they look hungry bro. When you turning the dome on? Are you using straight RO? Is that ppm meter just a ppm meter? Because 1.2-1.3 EC is 840-900ppm @.7 conversion. It is about 600-650ppm @.5 conversion. So if your cheap meter is .7 conversion, You are actually right where you need to be, without diluting.

Hey Roasty,
Here are a couple plcs from my EC stick. The first is EC/PPM @ .5 conversion...

Here is the .7 conversion...

If it isn't useful, sorry. Just showing you what my expensive stick says. peace, slow

Yeah slowandeasy, I guess I should turn on the dome now? I was taught to wait for the plants leaves to exceed the pot, then fire it up. But you've proven earlier is just fine if not better.
Yes RO water that starts out at 45 ppm, and ph 6.5 .
I always have used the .500 scale when converting to EC, but I really don't know if that's right. Thing only gives a ppm reading.
They have greened up some since last pics this morning, so I'll wait till next watering and adjust.
I'm also wondering if maybe my scale could be off, that could also be why the mix came out too strong.
What ppm/EC should I be at right now?
Might just buy a new scale, and just trust what your feed schedule says to put in there. But damn I like to check that shit, probably need a new EC/ph meter as well. What kind you rocking there?
Appreciate you stopping by and checking it out.

You can look up your models conversion most likely. I have always used a Blue Lab Truncheon for EC. Your scale could be off? I would start your dome anytime bro.

Thanks slow!!
I plan to start the air today, and I'll check my scale with a nickel to see if it says 5g. Just not sure if it's accurate at smaller amounts. Does Bluelab make a combo EC/pH meter? That would be nice.

 

[Roasty McToasty]

Fired up the dome at 10 am yesterday, day 15 me thinks. Well I'd be lying if I said it didn't have an effect. Significant growth for almost 1 day. Going to add a tad of MC to the jug and give them a boost. Since I diluted and its a little weak. Fwiw I'd rather be deficient, than toxic, easier to correct.

They do make a combi meter picking one up on Tuesday if the dozy arse hydro shop have remembered to order it for me it's £179 there
