I grow DWC so I can only advise so much but, I thought they needed much shorter watering cycles, 10 sec on 50 sec off, repeat. That may just be aeroponics, but I'dbe concerned with a bit of overwatering, again im DWC so I could easily be wrong.

Do you have another option other than the rock wool? That stuff holds too much water and the roots will get oxygen starved. Almost anything is better than rock wool.

Thanks guys,
Ive not had an issue with rockwool before now but do agree about performance, there are not the best but works perfectly on nft table.
Started using the new Eazy plug which are amazing and would highly recommend them, perhaps the jump to the new medium plus a little over kill with the lights is the cause,
they were as happy as 2 ducks in a bond till i popped them into rockwool, how have red stalks which is a sure sign of stress
