Free weed to whomever helps me solve this

i was using the evolution RO 1000 + DI that comes optional with that unit. I think you can plum the post stage DI filter from that unit into yours since they are both hydrologic. What luck.

Thanks, I'm also sending a water sample off today.

It's a good idea. Another is to use ozone, it will oxidate and cause to precipitate almost anything out of your water after you RO it. I used to do this in a 100G drum. Then run it through a cheap inline charcoal filter like one you use for an RV that attaches to a hose. If you have a ozone generator swith airstone , that is way cheaper than any DI filtering and should resolve your issues. There is a formula for the amount of time you need to run the ozone per gallon. At that oxidation level though the ozone will start to oxidate nutrients, so wait 20 minutes before you filter it into your reservoir.

It's probably a calcium deficiency. I had something similar on a plant that had been getting tap water/hose water, then the rainy days started and I didn't have to water her again, until I noticed the deficiencies start. RO removes calcium, and coco often needs more calmag.

Well water

Yeppers!!! Well water would have been the first thing I thought of...

Before you spend lots of money you really should get water from another source. Water 1 plant with it and see if it shuts off the problem. Probably still something in the water you haven't filtered out or compensated for. What type of well is it? Is the water consistent? Is there runoff issues into the well?

You are running your coco pH at 6.0 I assume. Calmag since you are using RO?

Water test will be back in around 10 days so I'm currently hauling water from my other grow. I really don't think it's a cal mag or other nutrient problem as the super soil plants are showing the same signs. My other grow which is growing the exact same way has no signs at all of any of this. This is what has me leaning towards the well water causing some kind of problem.... I just don't know why

I'm not sure what type of well it is. I don't think there are any runoff issues into the well but this is the first grown at this place. And for the ph question. Ph is always between 5.8 and 6.2

800 ppm water going into your ro system? have fun changing out your filters every couple of months....hope they're not too spendy.
the only thing i've ever seen damage leaves that way were either ph being off, or root rot. if you had had root rot for this long, you'd definitely be aware of it. that leaves ph being off.....
i grow in coco, and stick right around 5.8. i have a decent dr. meter ph meter, and calibrate it every two months. so far, it hasn't needed it, but i do it anyway.

Well then you haven't seen a lot of different water sources growing I guess? I grow on well water with a 600PPM, as I mentioned earlier in the thread certain things saturated in solution will pass through RO filters, it needs to be precipitated to be removed. An example is manganese. Where I live the Manganous Mangaese is 500X the EPA limit from my well.

The first and the most common is technically called manganous manganese. In this state the manganese is completely dissolved in the same way that sugar or salt are dissolved in water. To be removed with a filter, manganous manganese must first be “precipitated.” (It can, however, be removed by a water softener in this form and only in this form.)
After precipitation, manganous manganese becomes a solid and no longer remains in solution. It can turn water black. This form is called manganic manganese. Precipitated manganese is easily removed by a filter, but it is not removed well by a water softener.

800ppm out of the tap, that's like Flint water.

Hopefully you've got some selenium.

Thanks for the info. And nope, never grown with well water. City water and creek water from the mountains. This well water growing is new to me, but it does taste good.

Id check for magnesium in the filtered water....or lack of it

IMO, with all that leaves in the flowering stage, they become a major sink for N, Mg, and S

It was new for me to. Although I have the problem licked with the RO system DI or ozone the process was too much for me in the filters were too expensive. Lucky for me I live right next to a lake and that water works fine PPM of 100.

One of the test came back positive for total coliform bacteria.

Somewhere on riu, somebody mentioned garden saver. Its a .pdf file from 2005. It has lots of pics and great info. Try to find it and download it. I dont remember if I got it from a torrent site or not.

Looks like early cal deficient to me.

I never had problems either, then I moved. Things went to shit. I thought it was my water as well. But my plants just drink more here for some reason. I'm adding double the nutes from last time. Eventully I figured out, its not the water......

Here are some pics from that.

The 2nd pic is the calcium.
