Hey guys, awesome set up ^_^ I noticed you’ve had some problems with yellowing of your leaves, personally I think it looks like some light/heat stress also considering your schedule says that the plant is only 60cm from your light which is far too close for a 600 and 400 watt hid lighting (I have a 315 watt hid which I find I have to keep a good 2-3 feet away during flower and about 4ft away from a seedling).
Check the manufacturers recommendations for optimum lamp hanging distance and adjust to that, all manufacturers recommend a different height so there is no black and white answer to “how high should my lights be” but you may find that it improves any issues you may have with your plant.
Happy growing guys and good luck!!!
