Yes, they will be just fine as long as you fix the nutrient issue. Other thing, have you knocked or brushed the flowers more than gently? Sometimes an elbow or maybe sleeve catches them, or when youre tying down you give them a knock, which causes the pistils to die (why they go brown, this is what happens when they ripen. The dying that is.). Happens to me all the time, part of confined spaces. As long as your plants healthy new ones will outgrow them pretty quickly. Just watch the nutes. I look at the very newest growth when assessing this, any change in the way of kinking, twisting, or even looking at me funny and I know the nutes are out. I go in .25ml increments which for me is 75ppm and can see if they've been overfed even by one increment the same day, be sure by the following morning. Getting on top straightaway is best and your plants always tell you what they want.
The sheen on the leaves suggests slight nitrogen toxicity by the way. Common in early flower, particularly as you change schedule. Flush and a reduction will sort it although unless its considerable you could have got away without the flush. Keep a proper flush as last resort always.
Anyway, you done good!
fan leaf tips turning brown too.
