Nutrient burn o defficiency? or what is it?

see how big it is? and im way bellow the nutrient ammount, it says to put 3 to 4 ml of nutrient grow, but im only putting 2 ml, and im washing from time to time

i moved my plants to their big boy pots as their roots were rootbounding.
as you see the older plant is at ground level, so i kept the others higher on a box,
you guys think its all good?

Just keep on feeding them them, Einstein...and see how that works out for you.

yeah one thing I understood about growing is that you learn with mistakes.until you find what's best suited.for you..anyways thanks again guys. great support
