- Some Nitrogen Curling on NL2 Dominant (Pheno #2) - Will REDUCE EC if doesn’t abate today . . .
- We have some White filmy scum forming on top surface of res water. Suspect Silica. Will clean out res TUESDAY and restart w/Out Silica Skin. If we’re clear FRIDAY - Start Re-adding until and unless white scum forms …
Reducing EC: 2.3 # Will reduce Day by Day to 2.1

- [x] Install Intra-canopy Light 50% Dimmer
Note: After H2O2 yesterday, and 1 cup (in about 2 gals) today - the amount of scum is REDUCED SIGNIFICANTLY. I filtered with hand strainer until there was no more film or particularate (there wasn’t a lot) - The overall appearance is better.
Have refreshed with 3 Gallons and Primer A&B Only (and SLF-100). We’ll monitor. If it stays clean, we’ll test again with Silica Skin Gen 3.
