Yellowing on leaves can someone help ID

i recently switched from using bottled nutes to using dry salt fertilizers, specifically, Jack's citrus, southern ag calcium nitrate, and epsom salts. use 1/2 tsp per gallon of jack's and cal. nitrate, and 1/4 tsp of epsom salts per gallon. 50 bucks for more than a years worth of nutes.
i add a little rhizotonic the first 4 or 5 waterings for young plants, and 1 ml per gal. silica till i flip them. i keep some cal-mag around but don't need it often, might add 2 or 3 ml per gallon for the first 2 or 3 weeks of flower.
you can run that all the way through, without changing it, or you can add a very little MPK (mono-potassium phosphate) during flower, or you could switch to jack's bloom booster, which is 10-30-20

man I hate the nutes

fox farm nutes are the worst

theres no calcium in any of them

they'll say "derived from magnesium sulfate" and list no magnesium in the % info

im just not going to offer any advise on how to mix this brand anymore

after looking at your bottles ive just realized I offered advise on these nutes before and it may have been wrong
so I have to go back thru my posts history and find the guy I gave bad advise to

sorry to be a bummer id switch brands

for now in veg

id use the grow and calmag only

equal parts of each

5mls each for those small plants

10mls each for full strength

get another brand soon

Would you recommend Advanced Nutrients Bloom Micro and Grow or do you know of another brand you prefer?

advanced can work but there likely the most over priced and shady

they split theyre mix into several bottle to get you to spend more on the water

techn flora is good but expensive and the directions are terrible

general hydroponics easy to mix and the driections aren't off much
either of the flora nova flora grow or the GH 3 part

the previously mentioned dry salt mix is good but youd have to learn somethings about dry sat before youd feel safe using it

tell me which your going to buy and I will give you the mix formulas

don't buy it until after I give you the formula because you wont need all of the bottles they try and sell you

for the GH products

the flora grow and flora bloom all you need is maybe additional Epsom salt..everything else is in it and within ratio parameter's


the 3 part mix youll need only the
grow
micro
bloom
calmag
Epsom salt

Thanks so much for the help I really appreciate it! I spoke with FF folks and they told me they dont include the Cal Mag in their products so ppl add that after the 2nd week. I guess i missed the memo that it was separate (seems silly). I added some of that and some molasses and saw immediate recovery. im going to possibly run the FF through one complete grow and then use GH for follow up grows, or switch to GH for flowering portion of grow.

For the GH products, do you recommend anything else as additives for Flowering portion that you've seen yield good results?

additives are more commonly just a way to get you to spend more money

these are good additives, but don't spend big money from the hydro stores

kelp
amino acids
silica
below are links to get all kinds of additives and with good direction without being taken advantage of... these products are better than the liquids that have been on the shelf for years

this is silica in powder form.... 150 grams of this powder mixed to 1 gallon of water is about the same as silica blast only itll cost you maybe $1 to make a gallon

many brands will claim to separate a portion of the calcium out in a calmag product because you may or may not have calcium in your source water and so it allows the user to tailor the calcium to his personal needs
but the truth is youd have to have a ton of calcium in your source water
my opinion is its just an excuse to sell you another bottle of water

While I was waiting for GH cal mag to arrive i blended washed egg shells in a coffee grinder and made a foliar spray of that as well as the epsom salt spray that was suggested (i believe by you previously). I definitely enjoy finding the cheaper DIY solutions to issues rather than throwing money at it so always welcome hints like this. Thanks

check your product info again to make sure I have the correct info
I have the grow 6-4-4 and the bloom 0-5-7
if that's what you have then;

id say your looking at mixing it like this

full strength

bloom per gallon
2.5 mls grow
7 mls bloom
8mls calmag

grow per gallon
4 mls grow
6 mls bloom
8mls calmag

that should work
there choice to force you into using so much calmag stinks for a few reasons
it ends up putting excessive iron in your mix
theres already plenty of iron on the base nutes and the calmag just adds more

and theres a large portion of N in the calmag that's adding to your overall nitrogen so the FF nutes really are not a good product ratio

not to say you cant make it work until next time

I really hate these FF nutes

the problem is, when your add calcium you also get something else with it! calcium doesn't come as just calcium

options for calcium

calcium nitrate (adds N)
calcium carbonate (raises PH)
calmag (adds N and Fe)
dolomite aka lime (raises PH and only works in soil)

your base nutes already have plenty of N and iron(Fe)


im not sure if you have calcium nitrate available to you
if you do then the fox farm nutes can be used in proper ratios mixed like this;

veg per gallon

4mls grow
6mls bloom
1.2 grams calcium nitrate (don't miss the decimal point)
1 grams Epsom salt


bloom per gallon
3mls grow
6mls bloom
1.2 grams calcium nitrate
1 grams Epsom salt

you can order it here

or you can buy it local at a farmers co-op for about $20 for a 50lb bag

Wow thank you for the nutrient blend info. I have Cal mag now using 1 tsp of it w/ a 5 gal res. I will check out the cal nitrate instead. Do you think that if i continue w/ cal mag i will eventually run into excess levels of N & Fe?

I have a EC & PPM meter now and basing my nutes use on 1/2 strength FF with 5 gal of water, im seeing about 1/2 the value of EC & PPM as recommended in the feed schedule. Should the EC and PPM level correspond directly like that? or am i way low in these respects? Thanks!

Ill upload new photos of the grow once the site has fixed the issue with photo uploads/posting.

Thanks again for your help + advice

The grow ratio is different for soil vs hydro with FF, so the Grow NPK is 3-2-6, not sure how that will affect the calculations

ec and ppm are exactly the same thing measured using different scales. some people like ec, but i find ppm is in finer increments which makes it easier to see what each thing i add does to the total....
or are you asking if you cut the strength in half should that be half the ec or ppm? in that case, yes, its a direct corollary, 50 units of nutes will give you half the ec of 100 units, its just a measurement of solids dissolved in your water, and actually, its just the stuff that conducts electricity, you can have a lot more stuff in your water if its non conductive

ok thanks just wanted to make sure i wasnt way off. thanks for clarifying
