Hello Mctuffet Well I'm affraid I'm going to be no help whatsoever here

That's what happened to my present grow as well. About a week after switching to HPS on the 12/12 cycle they just went limp and droopy, I put the MH back in and they picked up.
Anyway I tried the HPS again and they drooped again so I gave them a while under the MH and they picked up again
However since being back under the HPS yet again they seem to be ok.

Although there was quite bad condensation problems at the time in the growroom, I have been unable to say what the actual cause of the problem was ????

Told you I was going to be no help at all .............. sorry

Oh, it was thought that it might have been "overwatering" that could be the cause .............. I just don't know
