I would recommend copying someone's proven successful formula and then seeing how your cultivar responds in your environment. Then tweak values from there.
But whatever you do, copy JK or Yosemite Sam or Cap or Crysmatic or something first for nute values/ratios.

SAGE-LIKE ADVICE, MY DUDE
 
yeah, def running a different mix for veg. I was reading a lot of people talkin' about running 150-175 ppm K for 100% coco for flower.

thanks for tha review! might have to play follow the leader and use 3g of jack's and tweak everything around that. hoards of previous users cannot be wrong..

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.
 
look what i just happened to find:

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).

still keeping Ca at 120? Seems like some nute companies like to believe we can pump up the Ca, how high do you suppose we could take it? Would Mg have to come along?

I've got a friend claiming using Mg at rates of 250ppm...that seems a little outrageous...
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.

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.
