Hello, I posted a comment in the last post, but I didn’t get many advice, here I need your helps.
I live in an area where Masterblend is not available, so I make own fertilizer to use Hydrobuddy same as MB 8-15-36.
However, contrary to expectations, the lettuce I am growing has some deficiency symptoms, so I would like to ask for advice.
Currently, the light is provided at 9.5 DLI, and the temperature is maintained at (12 degrees -54F) and the humidity is maintained at 68%.
I would like some advice as to what may be causing the TIPBURN and yellow leaf symptoms like posted on picture.
Thank you guys!
