Week start: 27th March. Water change . During past week , had some issues with pH rising rapidly following pH down adjustments. Using Citric acid may be part of issue. Changed to Phosphoric Acid for pH adjustments. Also struggling with heat in tent due to Phlizon light output. Installed potable aircon to get temperature down.
Also - noticed some leaf discolouration slight, and some browning of roots (+ some slime). Added 90 mls Hydrogen peroxide (39%) to treat water. Monitoring effects.
Changed to Diamond XML 350 LED light. Phlizon 3000 raises temperature excessively in tent.
