I was still dealing with lockout problems until the end of this week. I flushed everything with pH'ed water and after that, gave her 3L of 1ml/L nutrient solution to compensate the loss. We went from 5.9 to 6.3 soil pH and as you can see in the pictures, it stabilized. I am now very cautious of when and how I water and feed.
I built some legs from ABS tubing for the elevated tray that helps when I want to empty the saucer.
The light is at 70cm, 80% power for 650PPFD. I might invest in a CO2 reader to know if I could give her more. I have to adjust the power and distance of the light to get the adequate room temperature. I'm aiming for the highest difference between day and night.
2 more weeks of veg and depending on the size, I'll decide to switch or not.
