Spectra 290 2011 LED leaf problem in Soil and DWC cabinet

can you point me in the right direction to a link documenting the issue. The 100w GLH spectra UFO is only 100 of the 690w of led I'm running but I would love to read up on other growers issues. I had my GLH about 7 inches above a MI-5 auto flower and it bleached the shit out of it. I've dialed it back and it seems to be working well, but have noticed the spectrum is way different than all my other panels/ufos. They employ way more diodes in the blues than the rest, even the pro grows which are 50/50 veg/bloom. I have the 2011 v1 model and its probably about 60/40 blue to red.

I only managed to save the aurora plant, which is now slowly flowering... but it still has loads of brown spots.

in the meantime I started 3 autos from seed, Auto assassin, royal dwarf and jack horror. Their growth seem to have slow down considering they are about 3 weeks from seed.
some of them even have signs of yellowing.

Auto Assassin


royal dwarf


Jack horror


I tried contacting Mike without response. A bit surprised on that, I thought a bit higher on him.

I cannot edit the previous post for some reason. Anyway, Mike finally replied to my e-mails. Exact quote from him:

"have had some people encounter a similar problem, I have been able to fix this problem by sending out new power supplies that lower the intensity of the led panel and this fixes the issue."

So i guess I found the problem. Lets see how it will turn out.

Hey Stealth, how'd it turn out?? I have a spectra 290w and I'm curious how your's is working out!

Ever get an answer?
