Help me!! Please :)

Hi guys,
Method :
4 plants
Norther lights
400w HPS
3 weeks into flower
Soil

Feeding - using H&G - 4ml per litre of each. I've gone feed , water, feed, water, feed.

Problem - all was going ok and now the leaves are throwing up issues - and it's spreading! I don't know what it is or what to do? Can this wonderful site help? Leaves are bronzing and browning... And going up the plant.

I have a feeling it's burn ? Pics attached. I did a little flush last night but it's spreading.

Thx guys!

More photos under natural light would help. (You've only got one photo of any usefulness.).

Overfeeding? Nutrient burn?

I hate to sound like a broken record, but when someone's 3 weeks into flower I think of salt buildup.

If you monitor your runoff ppms it will help you see if that's happening, and what level of ppm runoff is too much.

Thanks. I've just knock a brach and taken it off and noticed what looks like small seeds developing In the buds ... The buds of the lower branches !
Does this mean the plant has hermied?

Could be stress or genetics. Take a photo.

These are pics from the plant that seem to be growing seeds at lower branches. I've had this before

Look at the state of this one ....
