Hi All

I’ve noticed some bronzing on the top leaves of my grow. Any ideas what it could be?

Otherwise plant growing nicely and can’t see any other issues.

Thanks

Hey, it is showing cal def to me, if you use RO water you need to add cal mag every feed, but in flowering stages some times ppl feeding too much potassium that it causes cal def, im not expert by the way, hope you will fix it.
Happy new year

No worries - consider using just h20 till harvest being that you are in week 6 of flower - if you must use nutrients use at 1/2 amounts, you are in late flower and nutrient use can be1-2x.s per week -- if more it will in-terfer with the plant's 2nd metabolism were you essential oils and terpenes' increase/develope again

Hi mate 600w hps, I’ve lifted it as high as it can go after reading KM’s comment, it’s 20 inches away now.

I think I have another 4 weeks to go until harvest. I planned to flush the last two weeks.

ill give feed every other day just incase

If its only on the upper leaves exposed to that hps than its likely light. If you have more than that its probably nutrient related. How about a pic of that beautiful girl you have there.
