he is in water, dwc, you getting plenty of bubbles ?, , do the roots look ok ?, are you feeding half strength to start ?, changing the res ?

Yes plenty of bubbles just upgraded to bigger pump thought that was the issue.roots are good not slimy or anything a little brown but think it's from nute stain.i am currently using general hydro Lucas formula with the micro and bloom 5ml 10ml per gal was trying to make first go around simple but will be changing that after this grow. And I have been changing res every week.!
