I run 500Pppm in veg, of that, 210 is what's locked up in my water, so technically, I'm only feeding 290 in nuits.

Just took this pic for you, this cutting is 4 weeks into veg, and fed how I've just described. Don't lose heart dude, you can spin this round.

It's just so bloody frustrating! Never had an issue like this but I've never used water this hard before. It a pain. One of the plants I flushed yesterday is looking very healthy again so fingers crossed I sort it! I'll keep you all updated. My girls are only 2 weeks and 4 days in to veg from a cutting so I'm not doing too bad.

When you say 4 weeks in to veg, do you mean after the cutting rooted then 4 weeks?

Yes, 4 weeks after the cutting showed roots through the rock wool.

Late update! Finally sorted them all. They're taking 5 litres every day now! 5 weeks in to veg and they're looking amazing now! Thanks for all the help everyone!

Well I'm in UK too I just fill the bath a little with hot water, and sit my bucket of water in that while I'm mixing up and it should be near room temperature by the time you're done

All sorted now mate! Thanks for your help :)
