Man call me a hobbyist, and i am, but i feed about half teaspoon a gallon of hydro and half tespoon a gallon of calnitrate baby till mid flower then cut down to no cal nitrate, and some epsom all along... they dont burn they dont look hungry and the end result seems to be plenty enough in the jars and high enough octain to take me where im going...
Tho i do run mine through coco treated much like hydro so maybe the coco gives me some wiggle room to not be so precise... my girls can wick water/feed 24/7 and get top watered 12 times a day

if your using GH and your having all those nutrient imbalaces revolving around micro nutes... your either feeding too much or your PH is off
not likely youd experience a micro nute def unless your feeding less than EC0.8 or if the ph is off
over feeding often times looks like several def combined...
technically they are..when you over feed you get lock out and the plant doesn't get certain elements or theyre not available
so although your feeding heavy theyre still lacking
GH 3 part is also light on calcium and magnesium.. generally the mix requires abouit 2mls calmag and 1/4 tsp Epsom salt per gallon to balance the cation

theres a balancing act between the uptake of potassium calcium and magnesium
if one of these elements is out of ratio itll throw the whole thing off
to much potassium will lock out magnesium, too much calcium will lock out potassium and magnesium
looking at numbers youd like to get something close to a 3:2:1 ratio K:Ca:Mg
so if your K is 120ppm, youd ideally want your calcium 80ppm and Mg 40ppm
the only time this rule doesn't apply is during late late bloom when the K requirements go up youll see a 4:2:1 ratio will work
for example
K 160
Ca 80
Mg 40
but that's really pushing the K up to its limits and not something I bother with... I just feed the 3:2:1 ratio between K:Ca:Mg
so the ppm of Mg will always ideally be half that of the calcium
having said that you can see the jack mix you posted on hydrobuddy...the Mg number is very high (65ppm)
high Mg wont hurt anything but its more than required

Bingo!! It's easy(ish) spotting toxicities or deficiencies with a pair of eyes and a search engine, but lockouts due to imbalance is like the UNgift that keeps on giving. Maybe seasoned botanists can quickly spot shit like that, but a stoner like me doesn't stand a chance trying to troubleshoot a lockout. so while I'm trying to over correct for a problem that doesn't exist, I further neglect the root cause and end up double screwed. Thankfully, for me, it was never that serious, but the potential was always there.
I know you grow in rockwool too, have you ever tried croutons? I use both the minis and the chunks and love them to death! I've forgot to plug a pump back in many a time, and worst I've ever endured was a wilted plant that wasn't fed in 2 days. After a watering, they stand right up! I also use airpots for a highly aerated root zone. There's pros and cons, of which I'm sure you can guess both. Still, this method is near brainless.

always feed less
you can be slightly def from underfeeding and still produce huge healthy colas... over feeding is literally the worst thing you can do
if your underfedding you can always add more and it takes about 48 hours to correct...if your over feeding its a nightmare and difficult to correct and takes much longer
keep your EC at 1.2 max... youll be shocked
id not mess with the mkp at fist...just use the basic 3-2 mix and use it as a bench mark before tweaking it
also make sure your getting enough run off with each watering... if you don't put enough volume thru the medium youll get accumulation which is the same thing as over fertilizing
are you running a reservoir or is it drain to waste
if you run a reservoir .. manage it with these rules in mind
PH goes up and EC goes down = raise EC (maybe)
ph goes down or EC goes up = lower EC
if its dtw then youll test the waste and compare it to the feed solution
and use the same rules

I learned it's easier to fix a deficiency than a toxicity.
Edit - I adjust the epsom in HydroBuddy to 1/2 gram and that lowered the Mg down to 52.9, When deleting epsom, Jack's Pro gets it up to 39.9. I guess equilibrium is somewhere near the 1/4 gram range.

that's exactly how id run it... Mg slightly above the ratio is perfect... some plants are Mg hogs

15 minute recirculating. res changes once every 6-7 days. I'm experimenting with frequency and right now I'm feeding twice daily till mid bloom, than upping to 3 feeds daily, 15 minutes each. Very thorough flushing. With GH at least, I've been doing a mid bloom flush to prevent buildups and that was a game changer which helped minimize my imbalances.

Kush is a CalMag hog, though IDK if that was for the cal or the mag. I read that when researching the strain before growing it, and I have been giving 2 more ml/gal than GH required. IDK if I helped or hirt things in the long run.

how are you mixing the GH
is it the 3 part grow micro bloom, do you have the kool bloom?
im4satori
Well-Known Member
there are several mixing options with the GH 3part
heres one for example if your mixing bloom and don't have the kool bloom
per gallon
grow 6 mls
micro 3mls
bloom 6mls
calmag 5mls
98 N
41 P
138 K
82 Ca
48 Mg
heres another bloom option
grow 2.5mls
micro 5 mls
bloom 7.5 mls
kool bloom 1 ml
calmag 2mls
90 N
58 P
132 K
39 Mg
83 Ca
and another option
2.5 grow
5 micro
10 bloom
2mls calmag
90 N
60 P
132 K
83 Ca
49 Ca
another option
0 mls grow
7mls micro
14mls bloom
92 N
81 P
138 K
Ca92
Mg 55
a 1/4 tsp (1 gram)per gallon adds 25ppm Mg
0.5 grams per gallon adds 13ppm Mg
heres one for example if your mixing bloom and don't have the kool bloom

I have GH's entire Flora series line except Diamond Nectar. Looking at nxsov180db's regimen leads me to believe I might be able to trickle out my CALiMAGic supplies over time but generally speaking, I'd be content to never use GH again unless needed. I have a pretty good dry nute starter kit and I want to keep fleshing that collection out. There's so much more control this way. Please review my bloom schedules Io made last night and make recommendations as you see the need? I got 5lbs of Potassium Sulfate to recreate Flora Nectar 'Fruit-n-Fusion as that stuff has made my Kush taste so sweet which actually complements the fuely/earthy/musky flavors well.

I'd also like to hear your thoughts about converting mass weight (grams) into liquid volume (ml) for easier references. I want to make the dry nutes into concentrates and I believe if I divide the number of ml in a gallon by 10, I can add that many grams of dry nutes to each bottle that would then allow me to easily convert grams per gallon into ml per gallon.
3785.41/10=378.54 grams of Jack's Pro 5-12-26 to one US gallon. If my math is correct, that would translate 1 gram of Jack's into 10ml. I'd then be able to reference my recipe for Jack's Pro (2.4 grams) and instead of having to weigh, I could just draw up into a syringe 24 ml of Jack's Pro, or multiply that 24ml dose by the number of gallons my res is.
I would then mix other components into their own respective gallon as done so for Jack's Pro.

My intent with the numbers I used is to convert one gram into 10ml. This way, if I need to change the dose or the whole recipe, I would be free to do so.

looks good
btw..don't count on the EC numbers hydrobuddy provides... itll turn out higher than what they say

I'll do a dummy run with 5 gallons of RO and intentionally under dose it to about .7 .8.
Do you have a balanced veg recipe to share?
