Started to give nutrients at 440 ppm and finished the week at 470 ppm.
Now changed the sprinkler cycle to 5min/20min
Lights increased to 80% before mid-week.
Looking good, the stretch from flowering is exciting. With the light penetration you mentioned, should see some decent sized buds on that poison berry. My first run of it was outdoor during winter, just 1 plant. Genetics are nice but mine yielded low for obvious reasons. My recent germ didnt take so I have my last two soaking now. I’m excited to see your harvest, keep it up
