3CFL's 1350 lumens each-Ph 6.7 she was ok 'till today.... (((((

kind of looks like it might be a mg issue because of the yellowing/spots, could try adding epsom salts to your water.

Thanks sm315, I added some epsom just about 4-5 days ago.....it seemed to like it.....then boom all of a sudden....may-B I need some more? I'll give it a try
Thanks from the advice.........1st successful grw
