Could the yellowing by light burn?

WOW LOOK AT DAT!! LACK OF REAL INFO IN DA DIARY!!! NO CLUE IF YOU ARE FEEDING SALT OR ORGANIC TYPE!!! CAN ONLY GO BY A FEW PICTURES!!! PLANT LOOKS LIKE IT HAD A LACK OF PROPER NUTRIENTS FOR A WHILE!!! WHEN YOU FLIP TO FLOWER STILL NEED SOME N AND START RAMPING UP DA P AND K!!!! LACK OF DA PROPER NUTRIENTS GAVE YOU DA EARLY FADE IN MY OPINION!!!!
