Help Needed Please

I am in 5th week of flower. My leaves are dying at a great rate of speed. Could a kind farmer give me some pointers please?

120 liter tank with 3 cheese plants in it.
RO water
50ml Bloombastic & 120ml Plant Magic Magi-Cal up to 400 ppm (.7)
Flora Nova Bloom up to 1350 ppm.
PH 6.0

It is happening at the higher fan leaves.

Any help will be greatly appreciated

Thanks

Some yellowing is natural. That doesnt look right though. Id say back off on the feed for a bit. Youre running kinda high. Could be some burnt leaves youre seeing.

Thanks, I've took the ppm's down to 1000 (.7)

I thought I would have had a few more opinions!
