Hi folks,
I have a 90 gal tank, running 2X2 54w T5's, 10 hr photo period with all 4 on for a 3 hr burst. I EI dose and use press. CO2. My tank has been up for about 10 months.
After the break-in period, I was growing plants with abandon. I was pruning like crazy, growing an assortment of easy and difficult growers.
Lately, my growth has really tapered off, with the lower parts of the stalks shedding leaves, less color, rageddy look, etc. I haven't done anything substantially different, and actually removed some of the sunset hygro (a super fast grower) to give the other plants a better chance.
I feel I have some kind of deficiency, but cannot nail it down. Absent of any signif. changes, I'm thinking maybe my light bulbs have decreased dramatically in intensity or wavelength spectrum. Two weeks ago, I increased my burst period to 6 hrs with no change.
My bulbs are generic, and came with the Catalina fixture.
any input would be appreciated.
Adam
