I've always believed and read is,

a perfect system will have a ph rise, water fall and ec flat.

Some people like to see the ec drop but I am not one of them. I like to see my ec stable and my ph rise while my water drops. In theory wouldn't you want your plant to drink and eat at the same rate?

that's absolutely fine

personally I prefer to see the slight and slow EC fall

that's just my preference because id rather slightly under feed than over feed

for me it feels like there is some grey area in the flat zone and imho theres nothing worse than over feeding even a little

but if I ran it a bit tighter or flat im sure it would be fine also....close enough lol

I should have put this here considering I started here initially.

I'm running the mix ratio for veg that @im4satori put up and if anything it seems I'm showing more signs of a cal/mag deficiency of some fashion.

What do you guys think?

The below pics are of the newest growth with clearest signs.

Exactly what numbers/ratios are you feeding? It might be more helpful to relate the photo to the feed.

Here are the numbers and ratios that were given to me by im4satori from hydrobuddy. I have been reading that there is some concern that LEDs can require the use of more cal and mag. If this is true, which I have resd some conveincing experiences, it could explain my symptoms.

veg

4-18-38 mix 1.5 grams per gallon
calcium nitrate 1.75 grams per gallon
magnesium sulfate 1 grams per gallon
N 117
P 31
K 125
Ca 88
Mg 52

I'm confused how to people give me calculations and they come up different.

How is it you and satori came up with different numbers?

Phuck!

I don't use a pc anymore just my phone and there is no hydrobuddy for the phone.

i'll ask again: how accurate is your scale? if you are doing dry weight measurements, i'd want something accurate to 0.01 grams

my 2 cents.

Scale is one issue I agree but its the same one I've been using with no issue. Will buy a better one just to be safe though.

As to the issue of two people stating the same dosages ending up with different nutrient ppms is a big problem in its own.

My dosages are either close as satori wrote or they're off as sky has stated.

i found the problem:

skybound didn't have mag nitrate in his calculations. @im4satori has that and mag sulfate on the previous page
That's my fault, I thought it was a reprint by accident, i do not have or use mag nitrate, I see and thank you both. Sometimes I miss having a computer but this is the first time in a long while.

Would adding calimagic help or will that increase calcium to much?

To fix Mg, use 1.75g/Gal of Epsom instead of just 1gr. There are still concerns with low Iron though. This is why I was not a fan of Jack's 321 and opted to use as many other products as I'd need to afford myself the ability to produce the best possible regimen. It's more brain work (and the need for a computer), but my goal is to grow the best pot.

If we can get it right with adding calimagic I canndo this and honestly already did. It's only going to matter till monday though when I get my mag nit on Monday. I added the calimagic before the post from sky. At the time I figured I'm going to switch it out soon anyways.

Thanks guys and sorry for misunderstanding!
