First let me say, Tried to diagnose on my own, couldn't find anything the same. I do at least have a good idea of what happened.

Light- Vipar Spectra 600 par LED
Indoor
Water-every 3 days or till I can lift cut and feel the weight gone or top soil dry, nutrients are seaweed and urb ph to around 6.8
Medium-Fox farms Ocean floor, red solo cups till transplany
Veg-Autoflower

It all started when I made some compost Tea with Malibu compost bags, my pen ph pen had to be re calibrated, ended up givng it a small amount of tea with PH about 4.9. Realizing after I started poring I want to PH again just to be safe. Recognized my actions and immediately flushed with distilled water and liquid seaweed mixed at 1ml seaweed per liter,

Initially thought was just showing signs of over watering because of the flush

then the brown spots started to appear edit:(not on newer growth yet)
then the edges of some of the bottom fan leaves crisping up,
tried to use guides to diagnose, im thinking soil may still be acidic and needs another flush or its a cal deficiency from the ph fluctuations.
Its been about 3 days now and soil is drying and plant doesn't appear to be stopping the spread of the spots
I really don't want to make it any worse so asking for help.

Thank You.

Nah im not im only using a cheap ph pen and ive been using tap water just bought a bunch of distilled to start using.

Im thinking im going to run down to the local supply and grab some cal mag and flush real good again just in case the ph in the soil is still wack.

Unless I get any better suggestions on here.
