This is most likely a phosphorous deficiency here... certainly not over-feeding. At this stage, you should be upping your PK amounts, not lowering them - but don't add any more nitrogen...
Good luck!

It is an overfeeding issue, and if this happens just lowering the nutes doesn't help but you should go water only for at least a week. I see you're also still giving 1ml/l of Biobizz calmag, that's a pretty heavy dose. You need to solve the lockout before you give anything more to it.

I've had tips burning probably from light too close. I find that leaves are pretty dark but it may be because of the strains. When leaves do get darker in flo ?2 years ago
