Nutrient burn or deficiency?

Yep, ph too high. That's why you are having troubles for sure. Get it down to 6.0 to help the Nitrogen availability. Feed at 6.0 to 6.2 for a couple days. Not sure who is helping you here?

If you needs any specifics, let me know.

Waira was here. He's the man, as far as I'm concerned. @MedCzech I see you around, offering solid advice, keep it up. AFN lives off that.

Cool thanks. Just an old stoner trying to help the next generation and/or anyone that needs it, as well as I am learning a lot of new things.
I have been in the shadows and never even really talked much about my gardens in the past, so this is a nice change of pace for me in a subject I have a wealth of experience and maybe even a little knowledge.
My normal work involves very deep analysis, so those skills were transferable to this hobby, and I have taken a slightly different approach in growing based on a combo of what the science says versus feel and instinct.
I love AFN! So many great people with other ideas. Sometimes I don't agree, but it is amazing at the results they seem to get. Our unique environments, where we are located on the planet itself, the energies around, the topography, from worldwide environmental variables to the most minute variable like maybe exactly the moment when to switch to bloom nutes and how. There are so many variables, that each grow seems to be quite unique when you dig deep.
There are multiple lifetimes of studying to do, so the best way to speed up that process, is to come here and get that knowledge for free in an accelerated time frame. Win for everyone here. I get more than I give, because giving is the gift.

Thanks for letting me be part of this worldwide family!
 
the flushing may help the pH, but it also stripping out nutes, and it's really showing now,... That soil blend may be part of the problem, which sometimes doesn't show until later in the grow as things change in-pot; symptoms are definitely mixed, makes me think there's some actual root trouble, which in turn can cause uptake problems and resulting defc.'s...... A root tonic and inoculants may help with this down the road... Water looks good at 7.1, but straight run-off isn't a reliable indicator of actual in-pot pH,... was that after you flushed? 7.1 in, 6.6 out, that's pretty strong acidification, so it hints that the soil has been, maybe still is a bit too acidic... do you pH adjust the feeds?
 
Yes I ran 3 gallons through the pot let it drain out. Then I mixed 1.5 grams of MC in another gallon that I tested the runoff from. I havent adjusted the PH of feed before.

It still lives! The spotting and browning has stopped. Most of the badly affected leaves slowly turned yellow and died, I removed those. The new growth has no spots but the leaves color looks off to me.

Looks like ph too low maybe and locking out Mg. Are you checking ph every feeding and using and Cal Mag in your feed?
 
You MUST ph balance your feed for the plants. Not an option to not do it bro. They will green up nice if you can get the ph right.
 
Here is a pictures showing my other plant. The 3 gallon pot dried out faster than the 5 gallon so my GF watered it more with too much MC that is what started the poor plants downward spiral. Today is only the second time I will be feeding since I made my first post in this thread, I will be using 2.5 grams of MC per gallon up from 1.5 grams the last time.

I will not be using 3 gallon pots any more the margin for error is too small when feeding. I have ordered some 5 gallon smart pots, soil PH meter and a better PH meter for testing the water.

Once you get the tools you need, the grow will become a lot more precise and the girls will show you there's naughty bits!
