I have been growing outside for a few years now, and decided to start trying at dialing in an indoor operation.
I am using the same organic super soil that I typically use outdoors. It's consistently brought me decent results. I had a little issue keeping up with Nitrogen last year, so I upped the amount of Nitrogen amendments this year hoping it would solve the problem.
It took me a few weeks to get Temperature, Humidity and VPD down, but I think I finally have a good range with those regards. Averages include:
Temp: 82F Day / 72-69F Night
Humidity: 64-68% with a slight spike to 75 in the hour or so prior to lights on (my dehumidifier isn't keeping up)
VPD: .85 - 1.2 average
All that being said, I am seeing extreme leaf curling on one of my autos that I am running (whiskey zulu). I am also seeing leaf discoloration which is making me think Nitrogen might still be an issue, even with my adding more than typical this spring to refresh the soil. I am also seeing a few leaves with copper speckles.
I am not seeing this on any of the other plants, minus the suspected nitrogen issue.
I have included 2 shots of the leaf curling and another shot of a photo that is going outside in the near future showing yellowing. A second auto can be seen in the background also with yellowing.![20240509_170547.jpg](/data/attachments/4494/4494251-31fd38d7de857c2000326ce93809ae36.jpg)

I am thinking I am going to feed fish emulsion to the plants to see if that helps, but any input or questions are appreciated, as I can't quite figure out the cause of the significant leaf curling.
Thanks in advance!
