mg deficiencies

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!?!??

anybody!!?!?!?? :-)

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.

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!!

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.

the whole reason I foliar fed was to see if nutrients were locked out after the problem had existed for a little over a week...

exactly nutrient lockout!! that's why I posted in my previous post that when the problem persisted for a few weeks I started flushing with distilled water and then after that ran light dose feeding again in the distilled water... during just water flush I checked runoff ph and ppms and I had a ph of 6.7 and 800ppm(again this is runoff of distilled water that was reading 30ppm going in) Would that indicate enough shit in soil to cause lockout??

Please read previous post!! But to shovel and polish would you two be kind enough to look at my two other current threads (are my outdoor girls ready & partial log multi strain) as I have other current question that id really like some good feedback on and you guys are always great, and im not gettin any answers from anyone else anyway lol! Thank you so much in advance!!:thumbsup:

Over the years, the term nute lockout has always been real popular. The funny thing is, no one in net forums has ever offered proof that lockout is really that much of a problem. I don't know how the use of this term got started, but even way back in 2000 on Overgrow, people came up with the strangest things to explain why someone else was seeing strange color on their plants - everything from "dude, check your pH," to "dude, lockout," to "dude, maybe you've got a cat that pees in the buckets." (Actually that last one was mine which I wrote as a joke back then).
So, to deal with this issue, the thing that in my opinion is the best solution is to understand that controlling a grow doesn't make it better. Use half-strength ferts is no guarantee that you're doing the right thing. Flushing and testing your ppm and pH is no guarantee that the information will help. Therefore, what many growers should do, is keep their grows as simple as possible. This means to grow as nature does, using bacteria and fungi to break down fert materials into a molecular size that roots can absorb. This is why the fert companies make powder ferts that either comes in boxes or bags. There are many other ferts to use, but if a grower puts one half cup of powder fert, like foxfarm's (in the yellow box), for every two gallons of potting soil, you'll probably see the success you're looking for. Once you do that, then if your plants show a deficiency you can use a small amount of a one part fert, one that has pretty much everything plants need, and give that to correct a problem. Just a small amount. But chances are you won't have any problems at all. You want to read the fert container and make sure that you see words like Bacillus and Mycchorizae, or however it's spelled, as these are the biological parts that will break down ferts to a level that plants can absorb. You can try other ferts and I usually recommend Dynagrow as it has pretty much everything plants need, but what the containers for any fert don't usually do is tell you how often to feed. This is where a lot of people get into trouble. The powder fert method is just water and forget it, unless your plants show an obvious nutrient issue. You can pick any fert you want, but you need to know what you're doing with many of them. I'm wondering if anyone out there is using the powders with success since I've been posting it so much over the years. If you're in hydro, the powders won't work. You need a fert that is designed for hydro. There are two other brands that come to mind, but namedropping is frowned on here.

Thats some great info buddy I appreciate it! Im actually usually pretty good with these issues and always get them resolved but this one just hasnt cleared up! Have you seen my journal for my current flowering girls? They have been great! You should check it out and let me know if u think its on point or if I have some issues theres a link in my sig:-)
