@GrowWithFlow, thank you I be chopping big one in next week started flush all ready
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
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?
