why in the fck would you say that ???? no its not normal obviously theres a defiency most likey nitrogen
IMO i would suggest getting calmag / super B max in most hydroponic flower food A - B there is nitrogen but not enought so you got to add supliments like super max B and or cal mag to compensate for any defiencys in flowering most powdered flowering products that most growers will add in flowering is like 0 - 52 - 33
anyways op you did well i would suggest getting a few minor nitrogen supliments for your flowering stage when a plant is takin energy from the leafs can only tell you one thing your lacking something in your food
as for jelious green heres a pic 2weeks before harvest and there greener then your grass
