And a few pssss...

Any foil you have around.....get rid of it. If you don't have Mylar maybe some cheap white paint or anything white to help reflect.

At a month old young man (or young woman) with that kind of ph rodeo be glad they are still kicking at all! (And I mean that in a nice way )

I might even think about just giving them plain ph'd water (R0 or distilled of course) for a few days since they are a month old. I thought perhaps they were new-ish clones. I would get that advice from a wiser mind than mine tho......there are plenty around. Or perhaps Flora Kleen or ???
Just rambling really on this last one.....
