First grow ever. Will I be able to harvest this plant

Yeah dont worry. Leaf burn is nothing. Even if the bud gets burnt its no big deal. Your going to cut the leaves off anyways right?. Ive had bud that was almost white is was bleached out by being too close to a really powerful HP sodium light and it still got me stupid high. looked like straw thou and didnt taste like much but yours is fine. Good idea on stopping the nutes too. just run water from now on and you will have super clean bud with no nute build up in it. And any leaves that look really crispy or cooked- snip em off ok.
