Looks like it’s locked up to me? Do you water till runoff? Have you cked ppm or E.C. ? Wait for someone with a little more knowledge but looks like high ppm and high ph causing calcium to get locked out

Lots of guys use the strips but a cheap ppm meter will be a good friend !
Ultimately ppm and E.C. are the same thing just different ways to measure conductivity
Yes or you could use lemon juice.For sure. So what do you recommend? Acidifying the water next time down to like 6.2-6.5? Also the nutrients I am using dont say they have Calcium in them.
Mg, B, Cu, Fe, Mn, Zn but no Ca
Can I use 1M HCl to acidify? Im a chemist and have dilute HCl from my lab and figured just titrate the water until its lower PH unless I should use some other kind of specific product for plants for acidification/alkalinity
Edit: tap water is 7.0 and runoff (through the pot out the bottom) is closer to 7.5

Agreed ! Sorry gonna jack ur thread for a second, I’m having an issue with low ph in the promix from salt build up I believe , even after a good flush it seems to still be low do you think adding Some lime to the mix would help or hurt? By masking the real problem?I meant to add you need to know your runoff ec (ppm). If it is very low uour plant is hungry and if high locked out. Should be monitored every time. Ph is way overstated as cause on these forums. Tap water does not change buffered potting soil ph.
Try theseThis is what I was thinking... I water till runoff yeh. I have not checked ppm or E.C... I dont have the means to do so.
Im gonna invest in a good PH probe for this I think. The strips suck.
The other plant was treated the same way, and started developing the same spots but was further along so I just harvested it.
Try dolomite, tbsp per gallon in soil but might try half that at first in promix, I water it in slowlyAgreed !

Sometimes I even feel I should be feeding more! Lol so at leSt I know I’m goin in the right direction , thank youWhat were the final ppm’s? Also the low ph is the runoff ph so if there was excess nutes being flushed the runoff can read low.
I see this too and the ph is always back to about 6.2 the next time i water/feed after flushing.
I added lime to a couple when i first noticed this problem myself and it has raised the general ph a little.
The pots i didnt add lime to both went back to normal by next watering anyway.
Pro mix also reads very low off the bale until the lime charges in about a week after watering in.
And mine is showing about 500ppm 1.0ec out of the bag even hough it has no nutes. That also seems to correct itself after a watering or two.
Try these
View attachment 970101 regarding septoria, I had a big issue with it years ago, can be tough to diagnose
beat it with copper spray and sulfur burning I can't say for sure it's septoria but brown circle with a black ring around it can be septoria
What's your humidity, do you spray the plant, your recent runoff readings and other information like that would help

Looks like too much nutes and too frequent watering has locked out calcium.
Flush and feed only 25% strength back if needed and wait for improvement. Do not water til pot is very dry. Im guessing dryer than when you have been watering so far.
And if you use the third organic bottle as directed the micronutes are in there.
