anybody knows? guessed N-defficiency but found ou...

Hard for me to make out the colors here. The lighting is throwing me off. I will say though that the leaves look like they’re responding to heat. Either it’s just too hot, or the lights too intense. Plants will show more deficiencies in areas closest to the light as well.

Npk are the big 3, other 3 macros are sulfur, calcium and magnesium. Sulfur and calcium are immobile. Of all the other micronutrients they make up only a couple %. Tips of leaves are turned up which indicates crispy temps, back up lights or make sure canopy is not going over 86. Apply calmag foliar application on underside of leaves if you notice difference over night apply to medium. Good luck.
