Purple flowers LED problems

[Raw710]

Does anyone notice their flowers don't get as purple as what they would under an HPS vs. LED? Anyone know why?

Reduced temperature fluctuation.

My temp fluctuation is good only about 5 degrees. Was hoping to get some more options to work with. Thank you though

I was describing why there is less purpling.. day/night temperature fluctuations are usually materially larger with HPS than LED. Both minimum temps and min/max fluctuations play a role in purpling.

Could be down to running higher temps with led ? Due to the lack of IR off them

I had the same problem. When I added CalMg it went away.
