Have you tried different water to start with? If not I would suggest that route.

Sounds to me like you just revealed your real problem.

Sounds to me if the only thing that has changed is the move from soil to promix this might be your issue.

In addition using water with high alkalinity is going to cause you grief as well. You say it runs around 10 out of the tap? Then that is way too alkaline. And yes you got it will reek havoc with your nutrient uptake.

Please dont confuse highly alkaline water with the alkalinity on the Ph scale it is a different animal.

Here is a link that got stickied some time back. Check it out. https://www.thcfarmer.com/community...-effects-of-water-with-high-alkalinity.77509/

The purpose of this article is to allay some of these concerns by pointing out the difference between "high pH" and "high alkalinity".

I think it is a water source issue, Too much alkalinity.

think it was 2 nights ago now I took some clones out of the promix did the best I could to knock it all off the roots then put it in happy frog looking like night and day now I am just missing something with the promix


does using the ph down or up not change the alc/asid of the water??? so many ??? so lil time

side not I have had a clone in just the clone tray just getting the rooter cube misted for just about a week is the best looking plant I have that is a clone so the plants I put in promix went to crap one in just plan water champ

I was thinking maybe the ph swing is what is happing but then I remembered this just started with this set of plants in veg and I been using the promix for at least 6months and only had problem in mid flower

what happen something about how people all ways stopping in after posting info its been days and days from any last post

I hope you get this resolved. It seems this problem is growing in popularity with different strengths. I still get the same brown, rust-color on my fan leaves and smaller leaves before they dry up and die. It's gotta be ph flux combined with nute burn and stunted growth that creates some lock-up I think. It shouldn't be calmag def. because I use tap water and no perlite in my ffof soil. I use pure ffof soil so I already know everything was running hot to begin with. Well, I hope this clues you in. Gl.

Oh, and the cutting I took from the very same plant flowers with NO problem in the same (well-flushed and rinsed) soil. It stays the very same distance away from the lights. Thats a bigger clue!
