Jack's 321 with RO water = 121 > 221 > 321?

321 is 1.2 ec. 3.6-2.4-1.2 is 1.4ec. Tint knows what's up. Make sure your runoff isn't more than 200ppm (.4ec) more than what goes in or you have buildup
that's not what OP said: he said full strength is 2.2 or 2.4

those #'s are fine by me. i never go above 1.2

Dude wtf are you talking about ? This thread isn’t about you. This guy doesn’t give a fuck about what works on aeroponics. He’s trying to get some help to what’s wrong LOL.
you obviously have a reading comprehension issue.
have a lovely nite.

I'm personally amazed that you can run it at full strength and not have completely fried plants after a couple of weeks, let alone making it to harvest with only some burnt tips. I goes against everything I thought I understood about nutrients.

have you ever reads jacks feeding schedule you dumb fucker ? Those numbers you just said your fine with put you close to 2.0 EC. Just stop bro. You shouldn’t even be giving advice here. Do you even use 321 ? Let’s see some these pictures that make mine look like mids

That’s why people should be careful who they take advice from on these forums. More times than not, you have a guy giving advice on something he doesn’t even have experience with.

That's straight off of Jack's site for cannabis / hemp. 2.4 EC, in veg.
Yeah they just made that not long ago to compete with athena and floraflex that also run high ec. Great for big plants and a dialed in room. I see dudes running 3ec on ig

Just made this feeding chart? Big vegging plants? My plants have been above ground for two months.

I've only seen warehouse grows with 5ft+ plants using that high ec. I do the 3.6/2.4/1.2 gram ratio which was their original formula or whatever
That’s the formula on the 321 page. I just did the math and it comes out to 3.7754 grams per gallon for part A.

You run it that strong during veg or are you talking flower?

Yeah idk why it says the ec is that high because it only comes out to around 1.4ec. Usually use it all the way through for everything I just make sure I have good runoff for little veg plants but I will dilute based on runoff ec if they aren't eating as much for some reason. Temps, humidity, light, ect all play a part. Just started using led so getting it all dialed in again.

3.78
2.52
.98

That would technically be full strength but somehow it’s been shortened to 3.6/2.4/1.2 or just 321.
I know a guy running a facility that uses that first number but I don’t think any home grower would need to go that high.

I don't think it's 1.4 because I was cutting it down to that EC. I've had a long day and don't feel like converting the math that got me there, but I just mixed the 3.6 ect ect version yesterday and it came out to around 2.2.
