5/7 It felt like my pH pen was off so I recalibrated it. Sure enough my reservoir was below where I intended at 5.7. I added more water and brought the pH up to 6.1 5/9 New pH pen arrived today. I was losing confidence in my old Apera PH20 so I got the Apera GS1. Sure enough comparing the 2 gave different numbers so I’ll be using the new one now. 5/10 It seems I keep needing to lower the light intensity to stop the burn. While there’s not anything I can do now to make everything perfect, I do think I’ve answered a lot of questions with this grow. I have a list of changes I’ll be implementing for the next grow to prevent the same issues from happening again. The major points are to switch to 1 plant in the small tent instead of 2 to allow for more training on the plant, which will allow me to keep the light further away from canopy height. As for measuring light intensity, my PAR meter is probably questionable but I do not have the money for a fancy new one so I’ll be focusing less on PAR/DLI and just eyeballing the plants more to guide me.
