I've been running about 70° during lights on! and 60ish at lights off!That color purplish is a tell tale P lockout. It's like 3rd grade growing. Here is some examples of corn that dont supposed to turn purple.

Wasnt picking on him but purple leaves on GG4 is not supposed to be there. It's a P deficiency plain n simple. That pinkish purple. Low temps can cause it but only during photosynthesis.
Lights out cold wont matter.
this pic was taking mid day!
but your also right, bc I have been running out of nutrients in my soil, my sip was just way too small for this big of a lady!!! almost 2 weeks now, I've been noticing she's outta gas!
