Think my plants have a deficiency please help

So from what I’ve read I understand that it’s normal to have lighter green foliage on new growth and darker on old growth, my last grow went great no discolouration or extreme bright green leaves this time around everything was good until I used super b plus stress relief they started going really bright so my question is is this normal colour on new foliage or is it a deficiency? I’m currently feeding a 1 part organic nutrient system called medione currently feeding it aggressive stage so 15ml/ gallon and my water schedule is feed water water feed every 4 days and second question if it is a deficiency anyone have an idea of which one and the method of correction?

Thanks for all reply’s in advance
