Thanks everyone. I've been using 1/2 strength nutes for 1 week now.

Stinky- The leaf curl was going to be my next question. I was gone for 2 days and we are having an extreme weather condition with really hot and dry air. I raised the lamp and am cooling them back down.

Was going to ask if it looked like it was the heat or Mg deficiency.

Let me know what you think.
