Leaves keep curling up and getting glassy and wanting to dry out.

Dry air and Little bit dry soil ., 70%humidity Is perfect .... POT water 10% of the v³

From here soiil looks dry n compacted. Wet that soil and try to break it up around the edges careful not to damage the tap root. Oxygen pockets are just as important as water.

First thank you for the fast response. Now have vent on raised lights fan on high ph 6.0 gave more cal mag now 1.5 ml liter trying to keep humidity up. Wish me luck

The curling is from heat stress. Need more ventilation. Good luck!

Most probably a lowhumidity or heat issue. Either raise the lights, reduce temps or get some moisture on those leaves and in the air. Could also be underwatering. 🌱👍

That looks like heat stress, try ventilating the room to lower the room temperature. 600 watt HPS produces a lot of heat, do you have a separate fan to cool the bulb and output the heat out of the room?

I dont really think it a heat issue as the worst of the problem is on lower leaves denoting a mobile deficiency IMO.

To me it looks like PH and nuet uptake as I see some calcium def IMO. Given you seem to be PHing to 5.7 might want to change that to 6.0 just in case you are getting some error on your PH probe. Some variance being a good thing within that .4 range from 5.7 to 6.1, I try to hit 6.0 but wind up with 5.8-6.1 practically speaking. Good luck and feel free to msg me

move your light away little bit,and cool the plant more to reduce the temp.add more cal-mag (i saw u added only 0.5 mm) it helps with heat problems too

you have a heat problem my friend :D
