Ethos Apex R-1 in Autopots

I've made a few mistakes so far - I initially underfed these, then overcompensated and overfed them. It's interesting to see signs of nutrient burn. I'm still getting a feel for how long it takes changes to the reservoir to show up in the plants. I'm backing down the PPM to 1,000 and keeping it there for another week, then I'll start to taper the feed down. The buds look good despite the leaves looking a bit ravished. Stunted growth due to underfeeding at the start is visible in the plant on the back right. I've upped the calmag to 5 ml/gal based on deficiencies I experienced in my other grow. The smell is very mild.
