Royal Cookies Automatic (First ever grow

Plants seemed super short coming into week 3, I've raised the light 60cm above plant to encourage some stretching which it definitely has done this week. I'm watching the plant closely as moving into week 4 could mean moving into flower... They look pretty happy. Watered every 2.5 days, leaves and soil misted with ph balanced water morning and night. I'm toying with the idea of throwing in some far red light for 4 hours to see if it helps develop the plants more. 29.01 Far red light ordered aswell as a UV bulb. Plants seem to be doing ok, noticed a few leaves on RC#1 had curled tips so held off on watering for 3 days which seems to have done it some good. Snapped a lower branch on RC#1 during LST, wasnt a clean break maybe 60%? I've glued it back in place to see if it will bounce back. The brand feels floppy and lifeless at the moment but I've supported it properly so hopefully couple days it will repair itself. RC#2 also fell victim and lost a fan leaf.
