100 n 175k is what yosemitesam at ic runs. He kills it. 40-60 ppm P, 100 ppm Si, 120 Ca and 60 Mg I believe. I am runnning in veg:
120 N
40 P
220 K
120 Ca (and spraying with Ca25 every week)
60Mg
103 S
this gives me 1.6 EC at 5.5 with RO
For flower I just add jacks blossom boost .5 grams per gallon to get:
133 N
60 P
232 K
This gives me 2.0 EC at 5.5 exactly with RO
I just started this new regimin on seedlings and they are growing just fine FWIW.

So I just need to double check myself, oregon's department of ag is a great resource but when it lists the non plant food ingredients, it doesn't contain anything but what there is a percentage of under. So in this example, no IBA/NAA etc but .01% of B1, correct?

I've been wondering the same thing, seems like the OR database suddenly has more detailed entries for many products which were updated just this month. Lots of older missing/possibly-incorrect data there too, so def not a comprehensive resource by any means. Also, i have yet to find certain ingredients there at all (like triacontanol, but not even certain of any products that claim it).

I did not take the time to read in here much or to know how that formula is that uses 250ppm of mag but I would bet I could taste the dif of that herb and mine . JK

I pushed the Mg when I was using CNS-17, there was definitely a point of too much. Don't think I would mess with that high of Mg either.
Some have recommended a 4:2:1 K:Ca:Mg ratio, in my particular case it seemed to be appropriate, and work out well. Though I suspect the Ca:Mg ratio can vary a bit without serious consequences.

Some salts impart/change the flavor, Magnesium is one of them. Are you adding that much ppm to maintain a ratio or because your plants tell you to. If they are yellowing up as in a def you might try foliar spraying them. Maybe your having a customs problem at the roots, not letting enough through.

I have experienced the flavor change of too much Mg myself.
I started out with the 60 ppms of Mg scaled to the formula, but they showed lack. I wondered if there was an uptake issue possibly. That and the chow I have uses 25% coco, I believe that sequesters a certain portion of the Mg. That and my plant has OG heritage, so far as I have seen that is a common trait (OGs being Mg hogs)
So I had to go to 73.5 ppms Mg or theeabouts instead of 60.
Foliar was not practical this run for a few reasons, too busy to get into that. Want to foliar more personally.

Too much K will affect Mg uptake also. also talk now of the myth of K. perhaps a lot less K will be beneficial? Just like a lot less P.
did some reading the other day and also found out that N is probably more beneficial to root growth than P.
Did you know that there is like 5ppm of available P in soils, due to the fact the soil holds most of it and will not release it in the solution. also lots of K being held in coco. Just some food for thought.

Magnesium
Also (from ehow lol) :
Magnesium
- Magnesium concentration in a hydroponic solution falls between 25 and 75 PPM. This nutrient composes an essential element of chlorophyll, necessary for plant food. Along with calcium, magnesium determines how a plant absorbs other nutrients. If there is an imbalance, leaves turn yellow and the flavor of certain vegetables--carrots, potatoes and peas--becomes bitter.

MAP was good for roots JK was saying long ago, has some N.
When I ran regular-type containers(like 1 oz of production/gal of medium) I am betting that way more K was given in total ppms. My 25% coco chow, @ 3 gals medium/8+oz yield per specimen, I am thinking contributes far less total ppms K.
I like the high N:K ratio(1:2.5) much better than the 1:1.5 and 1:1.6 N:K ratios I ran before. The PK boost in last 2 weeks I think could be tweaked. I think JK said he bumped P from 60 to 90 ppms, and K from 280 to 320 in his recirc system. I think he also said he cut micro values down, and maybe Ca also during this time? I believe he said this was the last 10 days of feeding.
I suspect there is a bit of variability in optimal P and K values, dependent on mostly nute delivery system I am guessing.
All high and shit right now.
Hey maybe we should be taking regular root pics to better determine cause and effect relationships of stuff on roots, might create other correlations. I should get to that one of these days.
One of the reasons I wanted to move back to a bucket system. That and Lost's seal or walrus memes a couple years ago that was funny as shit.
"No you can't have my bukkits!" fuck I laughed hard that day.

I don't remember, it was years ago, I think he was drinking that night.
No idea if that thread would still be here, or even a keyword to find it.
