Please help with my plant. Is this nutrient deficiency?

[michael11221]

Hello guys,

What is going on with my plant? Under a 1000w HPS. flushed 1week ago down to 400ppm, Today added advance nutrients testing at 800ppm with 1.2l per pot.

Thanks again!

i believe it's either cal/mag or potassium deficiency
