Sick plant

...yeah, with the nutes release come the acidity, which will contribute to the whole Ca lock-out mess,... using rainwater with little to no pH buffering (low mineral content, namely CaCO3) is part of this,... as the plant takes up nute's, particularly cations like K+/NH4+, the roots release an H+, acidifying the root zone,... with no Ca-Mg going in, no minerals in the water, what buffering the soil has from _presumably) lime is overwhelmed or depleted by now,...
... excellent on the TDS! 1040ppm as a run-off is high, confirming the overfert'ing, and the increased acidity of the run-off confirms it's too low pH in there... What's your tap water like mate? An all carbonate Ca-Mg supplement is called for as well (General Organics CaMg+ is great)... flushing with higher pH water is a good call now that we know WTF is going on in there- [emoji106] pH-up will use OH- to raise the pH, but won't do shite for actual buffering like carbonate will,... that's why I asked about your tap water and it's ppm, it might be better for this job!

Tap ppm is low 60ppm. Ph of 8

I got this today.

use the tap..... flush the shit outta it then measure the last bit of run off
then my guess would be give it a light smack of the cal mag at the end but wait for
"the guy" lmao get his input...
don't mind me

Thanks to all that helped. Started to get the same thing in one of my other 3gsl pot with osmocote. Flushed them all as ppm is high and ph dropping.

Hard lesson learned. I did not water to run off on most watering. The media got hot and dropped the ph to lockout.
All watering will have a good run off from now on.
