Hey @Stephane, I think you’re right on point with how the new growth looks which is very healthy. To me just looking at the picture it seems she has said, “forget these two leaves.” I would continue to do what you’re doing and monitor new growth. Said leaves turn yellow or enough time goes by, you’ll cut them off anyways.
Update time!(Day 19)
Today I tested the pH Levels in my water and it was sitting at 5.4. Did a fill to top up my reservoirs and added 1ml of Basic to raise that number a little bit. Will monitor and adjust as needed.
Wish me luck
Edit: RH is low and will be adding humidifier.
Yesterday @GroboJason and I did the full calibration on the pH Probe.
Started out by gently lifting the cover and removing the pH probe. I noticed quite a bit of red/brown coloured algae growing on the tip of the probe. I cleaned it with the pH probe cleaning solution and the tooth brush that came with the kit.
Completed the calibration process with the included solutions in the kit and help from Jason. I was lucky because I was on day 21 so right after the calibration I did a complete drain/fill and I replaced the #2 bottle in the Grobo.
So far so good the #2 bottle hasn’t been touched which wasn’t the case beforehand. I will continue to monitor but I think that did the trick.
