mg deficiencies

[Indimaniac]

Ok so I have a log on my current flowering girls which are also seeing some of the issues of my new found problem! So I had been noticing yellowing in the margins on my girls in veg they are 4wk old clones in 2litre pots of roots green fields soil, they get the full line of go bio nutes, gonna be a scrog grow under 2 1k hid lights in cool tubes 24hrs of light I have only been watering every 2days (as needed) and feeding every other water (considered light feed) after I started seeing the mg def tiger stripes faintly I fed a heavy feeding and a week went by they got stronger I started using go cal mag every water still nothing growth slowed and some strains are lightly wilting(may be another issue) now after about 3wks theres a few crispier yellowing lower leaves and striping is heavier its a mg def to a "t" just like in all the def pictorals... so I started thing about the last few months of issues and it all adds up we had environmental issues effecting wells around here and I think my water is soooooo bad its killin my girls it reeks of sulfer so bad it burns ur eyes its so full of iron its orange and its got LOADS of calc and more salt than u could imagine its ppms are only at 250 tho!? The ph is a perfect 7 everytime but i thin between the minerals n stuff in it after it sits in the soil roots n pots it wrecking the ph buffers? Or its just sooo hard it locks out nutes instantly and time makes it absolutely wretched!! Even if I dont feed at all just water(with the well water) after a few weeks I see burnt tips ph issues and then lock out again this is with no feeding at all... im at a loss!? Bottled water always seem like hell, and ro is toooo expensive right now.. what should I do!?? In addition I just got compost soil ready but its sooooo rich I dont think my roots would be able to breathe and when u water it is just muddy Im wondering what I should add to aerorate(allow air to get to the roots) and increase drainage that would be best to suite mj any ideas!?!??

OK i have an update that stumped me... i foliar fed last night 24hrs later there is absolutely no change!?? what the hell is that!? i foliar fed with Humboldt equilibrium (cal mag with other nutes too) i thought foliar would show improvements in a locked out plant within 12hrs or am i wrong there and just havent waited long enough??

The key phrase here is "locked out".
You might want to ponder that.

And you do know that amendments are not going to fix the present damage, yah?.
How does the new growth look?

To aerate the soil, I recommend peanut shells, unsalted.
Coco coir is good too.
Sand, is worthless. (Don't ask)

Glad those choppers turned out to be a trivial annoyance.

Obviously the amendments are not going to bring dead plant parts back to life but leaves showing deficiency should return to normal at least that's what I've always been told new growth is very very slow and it looked a little pale but healthy for the most part I flushed all those plants today with distilled water and a light doose of general organics bio grow and I'm hoping that within a few days I will see it clear up actually i had begun to wonder if my PH could have gone far enough off that that was causing the plant to be unable to absorb nutrients... I did a run off test and my run off even after soaking and the bottom of the soil for 10 minutes was coming out at 6.8 6.9 and I also tested the PPM's of the water from the runoff and it was coming out at about 800PPM's as compared to the 0 going in, not sure if that is normal or not as that's the first time I've ever actually tested the PPM toff run off??

Never foliar feed this plant. It doesn't respond well. It looks like you have nute def but not necessarily magnesium. Well-rounded one-part ferts, those that contain a lot of nutrients as listed on the label, can probably help you out. Buy distilled water from a store.

[Indimaniac]

ran the plain distilled ph'd water through and it was at about 800ppms... all thats sounds good tho so I dont get it!? Ive been feeding and after testing the soil and run off bla bla its seems to just leave under feeding and I dont really see that cuz ive been feeding full strength nutes every other water and some extras in between!!? Doesnt make sense!!

[polishpollack]

maybe your nutes don't have everything plants need. Did the yellowing develop before or after foliar feeding?

too much shit and the good shit gets locked out. like a deficiency we make happen by adding too much shit.
