Northern Lights / Tangerine Dream

Alright this week was a crazy one. I noted early signs of some sort of issue, but I had yet to fertilize or PH anything so with the arrival of my pens that process began. I dosed all my plants with a weaker fertilizer solution ~900ppm then recommended and tested the runoff to find it at ~3300PPM. I checked the soil bag I used and saw it was soil + fertilizer. I spent all night flushing the plants with ~6.75PH water until most were around 1200ppm and the smaller around 700ppm. After a few days I’ve seen some cupping and yellowing on a few of the leaves as you can see in the new photos, but I watered them 1 Gal each to runoff last night (~72 hours since incident) with 7Ph water and the runoff of all was about 6.5PH . The PPM I got off the initial runoff of each was inconsistent, with the highest measuring 1660 and the lowest at 700. The average of all was about 970, and I didn’t mess with them in any way besides to water each fully. Despite everything they’re growing a ton and I applied LST to the few biggest. They’ve all responded really well to it and have bounced back And are showing new sites. Hoping to see improvement in the new leaves with the last plain watering!
