After my ill advised flush of organic im seeing some form of deficiency im thinking Calcium? With brown spots also noticing veins on fan leaves yellowing? Should i try a foiler spray of cal-mag or is that not advised? I amended the soil with some base earth dust but i know that will take awhile to take hold. Any ideas?

Never spray a cannabis plant unless it is needed to treat mold or bugs.

this unfortunately growing organically. I tried my hand at organic growing and had deficiencies pop up and fed Jacks to speed up the process

Is this the runoff or what you put in?
If runoff, pH is good, but PPM is low. If it’s been there for any length of time, then the plant is underfed. PPM (~1,000) or EC (1.0) is a good target.
No the .55 tds is just the water from the tap. Ill have to see what the run off is reading. When i flushed recently in which i learned i shouldnt have in organic soil i was around 2.4 tds on it.
Is your meter calibrated correctly? .55 seems pretty high for tap water. I get primo drinking water bulk from Walmart. Cheap and it’s made with Reverse Osmosis. It tests steady around 50PPM/0.05EC. If that reading is correct you might want to consider using an alternative water supply.
If living soil it is recommended to foliar spray any calcium supplements. Mag can use epsom. Calmag solution foliar also. Only other reason to foliar are as midwest says. Plus if you flushed living soil itbwill take a bit to recover. Feeding more nutes to get it to recover faster is not the way. I am an Earth dust grower and you just have to accept slower recovery. You can add more nutes but risk getting hot as the little critters break down the ED.
