Super Lemon Haze-need help identifying deficiency

From a fellow grower: I am growing your Super Lemon Haze in deep water hydroponic system. I have the problem seen on the leaves below. I check pH every day and it is between 5.5 and 6.5 most of the time. The temperature is around 78 degrees F. The TDS is around 1100 -1200. I have added Cal-Mag as it looks possibly like a calcium or magnesium deficiency. There is plenty of air flow and aeration in the water.

Target a stable 5.8.

The water in your DWC? Too warm. Target a temp of 72F to avoid root diseases and pathogens.

I would say you have three nute issues here. Nitrogen, Calcium, and Magnesium or Cal-mag. I ran into a cal-mag issue after I flipped a photo and changed fertilizers. I did not realize my new heavy on P and K fertilizer did not have cal-mag/molasses. Common for it to show up in the early flowering stage. I hope this helps.
