Mild burn?

I have noticed a couple of bucket plants have a slight fert. burn, a few leaf tips are brown and crisp. It has been a week since I last fertilized, not all the plants are showing a burn but they all got the same amount of fert.

Should i flush them all anyway?

Is there such a thing as a slight burn? Or will it 'injure' them even more as the days go by?

After a flush..............how long before you should fert. them again?

I don't think it hurts to flush and start fresh.. I'm not in soil.. but from what I understand it's safe to flush as needed.

There is such a thing as mild nute burn.. it takes about 3 days to see burn from ferts.. so if it's been a week and you are only seeing mild damage, I'd say you'll be fine.. but after you flush you should fertilize right away.. you are stripping the soil of all nutes when you flush.. your plant will still need them.. and if they are at the right amount you there shouldn't be any further damage. If you have mild damage, you likely only got a little carried away.. so just back off a little bit and you should be golden.

Thank you kindly for the help!! I was worried that more damage may occur. I will flush and fert again to be on the safe side. I would hate to lose even a gram at harvest time this year! Next years harvest is a long, long way off! hahaha
