Yes They was being slightly ova fed bro but then i did back down on ec for couple days followed by plain ph water feed for x2 days then somewhere between this started happening.
I checked on ec runoff last two days and its been going in at 1.2/1.3 and cuming out at 0.8/1.0

I reckon you could still do with dropping that ec down to 1.1 if you can mate. Maybe even 1.0.
It's the plain ph feed that's done it, you shouldn't really just give plant in coco water, unless you're flushing.
If you're doing a mid grow flush, flush the fuck out of them, but still feed them straight after so the plant always has food in the roots zone.
If the medium, has less food in, than the plant, the nuits will leech out of the plant, and into the medium, to balance out the concentration ( entropy n shit). This is why those leaves have gone dodgy I reckon, leeching

Thanks for explanation brother. Im just waiting for the rez to heat up to 19' and i will be feeding them just a&b canna coco to ec 0.9 - ph 6.2
See how they get on with that.
I understand that the leafs wont go back to green so just gotta watch out for further yellowing etc.

Go for 6.0 if you can mate, just that extra bit of help
