Deficiency under quantum boards

I have a plant being grown under a hlg 600h r spec in a similar grow medium promix/growilla veg mix and they are doing good in the low 80s? does ur mixture have any dolomite lime in it?

To early to say this rise from 60f to 80f is a recent development. 3 days

I'm new here but I have been growing with boards for going on two years. You need to keep the temps at around 78 to 80 degrees and RH 50 to 60 %. . I use an all in one nutrient and a PK booster nothing else no cal mag supplementation. I grow in soilless mix 4 gallons per plant.
