pic 2 is odd. it still looks like its a little low on N, but the damage on that leaf looks like it could be bugs too. have you looked under the leaves? if its not bugs, then your pH is causing structural damage to the leaf, and thats no good either. im less likely to go with that tho, pH does some really funky shit, and that leaf isnt that wierd, its just damaged.
either way, mix your nutrients like normal, and raise the solutions´ pH to 7 or even 7.5 and add it in. dont add in a ton of nutes... yet
