yes it is a sign of very early abundance of nutrients but simply you don't need to flush.Only flush if you start losing more leaf surface.I mean,if signs get bigger and more parts of leaves get brownish,crispy,weird looking,you should flush.Since you are in coco,do not skip nutes.If flushing,flush with sufficient amount of pure water then give some nuted feeding solution.At this point,you don't need to flush,just decrease amount of nutes for that plant for a week and watch if it increases or not.Unnecessary flushing will do more harm than a very very slight nutrient burn,trust me.I've experienced it a few times before. But... I see you are giving 4ml of each one and this is %100 of what it says on the bottle,right? No need to feed that much in my opinion,especially in veg.I would immediately cut off Bloom part and back off with Grow nutes to 1ml at least.Good luck.your plant looks great
