Leaves Brown/gold in middle spreads out PICS

started noticing little spots a couple weeks ago. Now theres around 10 large and small fan leaves with this brownish gold shit coming out of the middle and spreading out. flash on cam is weird. Help me please !!!!

having same issues, going to use epsom salt on the next watering. I'm assuming it's Mg deficiency, anyone's input would be appreciated. ttt

whats mg ??? and is it in a 3 stage nute i got the micro grow and bloom ??? and whats epsom salt do???

growing soil or hydro? mg is magnesium. tends to get locked out at higher ph in water. i'd flush with ph'd water and make sure your mix is not too strong.
