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

I skipped watering them today because they aren't taking up much. I was feeding them based on the runoff EC for about the 1 1/2 months, and got them up to around 1.2. Then I put them into my flowering tent. They had gotten overgrown and some of them were weak from leaning on each other in my veg room, so I was keeping it around 1.2 ec. until they seemed strong enough. Then I started noticing the mag deficiency, but not N, so I assumed part A was fine, but B an epsom were too low. I increased the EC a bit, and it didn't seem to help much. So I came here with my ratio question. I was also mixing 3/2/1, not 3.6/2.4/1.2.

But now that I'm looking at Jacks chart, it says 1.1 for clones / seedlings / young plants, and then jumps up to 2.2 for vegging plants. That makes sense of my observations. The strength was gradually raising with the young plants until it maxed out at 1.2. At that point the strength needed to double instead of continuing to slowly raise. The plants are wanting adult meals and aren't satisficed with happy meals any longer. One or two extra nuggets isn't cutting it. It's a teen and needs a large combo meal.

Lol well you can use calmag if you need it I started doing 321 in ro with 100-150ppm calmag and it was fine. Tried without calmag and a couple did get a little mag def but haven't had any issues since bumping to the 3.4 and cutting out calmag

I've been watching this. It lead me to on a side quest where I found out that milk is filtered blood.

Skipping feedings is only going to compound your issues.

your base nutrient already contain enough magnesium you dont need to add much
but if you use RO you sure need calcium
get some calimagic, its based on calcium carbonate and a bit of calmag

1.2mS is not enough for vegging healthy plants
2.0-2.5mS is better

control your runoff; ph, EC

You do NOT need CalMag with Jack's.

Also my last run I never went above 1.2 EC all the way to harvest. A blanket statement like that is just incorrect.

my numbers are for hydroponic
do you use hydro ?

i dont specifically know jacks but i assume its designed for hard water, with relatively high levels of calcium carbonate.
if you use pure RO water (i only use 100% pure demineralized water from my air conditonners) you need some buffer in the solution
i use soft water nutrient formula (way less acidic) and even with this i need some buffer for my solution

lol dwc .. you're funny
if you feed the whole grow at 1.2mS you probably have salt accumulation in your medium .. so you feed less to counterbalance your clumsy management of the medium

classic for amateur coco growers
and i bet you use DTW .. lol

i use rockwool with geotextile felt for your information .. but no matter same rules also apply to coco coir

check your runoff EC .. you will be surprised

another prick that need to be agressive to prove his point
internet tough guy

I made a statement you disagree with and you call me a prick and an internet tough guy? How was I being aggressive? Relax buddy, we're having a discussion.

The ratio stays the same regardless of the dilution.

Yeah. I’m saying it has a bunch of cal as long as you don’t dilute it. My original question was about adjusting the 3 while leaving the 2 and 1 at full strength instead of diluting it overall. That was before I realized you were supposed to run it at full strength in veg.

You should always mix it at full strength and dilute to the EC you need for your plants. Then adjust the feeds based on what your plants are showing you.

I think the strength may need be adjusted if you aren’t running really powerful lights. In my flower room I’m running multiple DE lights so they seemed to consume everything I was giving them. If I was in a tent with lower wattage lights , I’d probably back off to 321 exactly and see how that did.

that quote was @farmerjoe420. yet he says to run full strength no matter what. seems like he's full of shite like i thought.

check and mate, jabroni.
