i would switch the lights and just slowly work your nutes up better not enough then to much off the start!! i never had much success using nutes myself always burned them up or had some kinda problems and lockouts..
i use my homemade liquid seaweed extract, molasses, and banana peels during flower all in a top composted manure with peat moss and black earth soil!!! makes beautiful buds, no worrys of over doing anything with nutes..
feed your soil and it will feed your plants!
i have friends using nutes some are doing ok others are doing sadly its alot of work feeding a plant, and guessing how much of what it needs and what it wants..
