For my grow lamp settings this early on should I be using the VEG And Bloom spectrums simultaneously? Or just leave in Veg? Since these are Autos I wasn't sure if switching the spectrums was as important as maximizing light.
I recommend leaving it on only veg for the 1st couple weeks, then putting the bloom switch on also.
The bloom switch is mainly red spectrum lighting which will encourage a little more stretching, but in my opinion, it is better to have a diverse light spectrum.
good luck!
