For some reason she got a little nute burn despite the PPM's being only 150ppm, she seems pretty sensitive at this early stage so I did not give any PH perfect A & B this week, I only gave her root stimulates (2ml - Voodoo Juice, 2ml - Tarantula & 2ml - Piranha) per litre. PPM coming in at under 100. I have been using bottled water to keep PPM's low for the first 2 weeks.
