Do my plants need more food?

Hello everyone!

Growing hydroponically in perlite. Ec 1.2-1.4


Take a look at the leaves, what deficiency is it? Week two flower.

Thanks for any feedback!

the leaf tip curl there in the last pic looks like a mag deficiency to me, is your pH where it needs to be?

What's your PH?...Im seeing brown tips on a lot of your leaves, I'm not sure that I would advise to add more nutes or at least not unless someone more experienced than myself stops by and recommends it.
