The RQS Bluematic seems to always show yellow tips, but you don't seem to have been very affected luckily. :) I guess it's a bit more sensitive to nitrogen?

To be honest it's my second grow I think I planted to many but they seem to be coming along nicely all plants are rqs the tsw I would say is really good and running cost is perfect planning to get another tsw in there next grow
