    Introduce far red mid flower?

    Hi guys, I've just received 2x 30watt 730nm cree LED light bars Would I be causing the plants to shock if I introduce the lighting in week 5 of flower? I have a 2mx2m tent Worried introducing a new light cycle this far into flower might shock them and turn hermie. Thoughts?

    I've got the purps

    3 week old seedling, local strain. Been under a far red spectrum LED for the last few days. I realize this isn't the spectrum it needs at this stage but it's what I have. Going under 3500K soon. Temps are between 50 and 65. Just receiving water. Any idea why it turned so purple?
