yellowing leaves 6 weeks into flower

Here is a pic of the bucket before a clean out


Looks like heaps of dead little roots floating around. Is this normal?

Here's a pic of the roots.

Too much potassium or mag can cause calcium def / lock out .

lack of iron and potassium can cause molybdenum and zinc defs too.

I did feed pk 13 14 . Four times in 2 weeks at week 3 and 4 when the problem got worse. Maybe this is why

You should be able to harvest them before it all goes too bad but if you are worried that it may spread then use some calmag for a week and then start flushing.

Bump.... can someone please tell me if it's normal to have millions of little floaties in my bucket (I think they are roots) can someone please confirm. As picture above.
Cheers
