I thought so too with the t5s but these are only half as long as I would have with a t5 and are 13w vs 54W so two across would be 26w total for each bank, but yes I was thinking I might be cooking them with too much light. The one indication that I may not have too much is that the dead stuff is all the old growth and closer to the substrate (and possibly shadowed) while the bright green stuff (which I am pretty sure means iron deficiency) is closer to the light. Am I off?
For removing the decaying parts, it is ok to just cut off all those leaves and have a bare stem? I would hate to to send the plants into further distress. Thanks.
