Wedding Cake Autoflower - Barney's Farm

Plants are 21 days from sprout. Notes from week 3: 1. Over the course of the week I bumped the light up to 30 DLI, will be increasing this week. 2. Started some gentle bending with the trellis net in order to get some light down to the lower branches. 3. I'm still seeing significant differences between the plants in the runoff TDS. The PPM for MJ1 (now on the right) is consistently higher than the input (by around 100-150 PPM) while the PPM for MJ2 is consistently lower (by around 50) than the input. Still no clue as to why this is the case. Nevertheless, both plants look pretty healthy to me.
