I was away for a couple of days with my family and so I could not take the usual pictures that signal the end of the week.
I changed the lights to the 100 watts strips and increased the light distance to 16 inches, with the increased light distance I have noticed a few thing: (i) the leaves are real big, (ii) There's no purpling of the stems.
I also increased the EC to 0.4 (cal-max only); next feeding I will start some grow nutes to power the stretch and maybe some bloom nutes.
The only reason this strain is at the same height of the others is because I've been using LST to keep the stretch to the same level of the other plants.
