<span class="link_user">@CloudJ</span>, how are you calculating VPD? Iām looking into this now as I havenāt considered it in the past. I also thought it was a light issue and itās been much better since moving plants away. I did feed them their week 1 nutes earlier than I thought Iād need to and it helped boost growth and vigor. Out of town but will update the week on Sunday! Maybe you can take a look. Iād be happy to provide other environmental measurements if you think the VPD is an issue.
