I thought so, but it just dosnt make sense to me i am under feeding them with nutrients probably by half of what the recommended chats says,

Can I still save those babies and if so how?

1 EC is not really underfeeding them. the "chart" wants you to use more nutes so you buy more nutes.

have you been giving them 20% runoff when you feed?

i would feed them with a nute solution of about 0.3 or 0.4EC with plenty of runoff for a few days. measure the EC of your runoff and i bet it's way higher than 1EC

So drop the ec levels much lower il give that a try hopefully it helps them to street out for the last 2 to 3 weeks

Well I flushed about a week ago and there was alot of ec built up, the run of was like over 3.2 ec so I think that's where the problem would started of.. only if I flushed a week or so early it would of helped alot..

Now my run of is at 1.0 ec same as what's in my tank but I think the damage is done..

Thanks for your help I much appriciated, so you recomend lowering the ec levels to 0.3 and water for longer period till there is about 20 percent run off?

yep. do that for maybe 2 or 3 days. measure your runoff. when it starts getting closer to 0.3, then you can slowly bump it back up. every time you feed, try to get 20% runoff.
but that 3.2 was your problem. that burnt the crap out of them.

The yellowing of leaf edges does look like a copper deficiency. Imbalances are to be expected when over fertilizing. Too much Phosphorus, for example, interferes with most of the micro nutrients.
