75 PAR... asking for trouble

I have a 125g with two 3' ATI Dimmables suspended above it. Tank is heavily planted, CO2 injected, EI dosing, etc. The question I have is whether 75 PAR at substrate level is going to be too much for most users or should I be ok as long as I have other things pretty much nailed down within reason? I'm growing HC and Glosso for foreground, but also have chain sword, micro sword, P. Stellata, and others. Light is about 26" above substrate and current peak intensity is only 29%. Currently running 1 hour ramp up, 8 hour peak, 1 hour ramp down. Tank has been going for a few weeks now and everything is growing fairly well. Best Cabomba I've had yet in terms of not getting too leggy, but the Shinnersia rivularis is growing like an absolute weed. HC and Glosso are growing well too.

Basically looking for anyone else around this PAR level and whether I have the window of perfection (CO2, ferts) too narrow with that much lighting?

 

Ok, thanks to both of you. Great to know. I'll let things fill in a bit more and then see where I'm at and maybe increase back up to about 33 - 35% which will give me close to 90 or so. I want to wait and see how things go for another week or two and also let things get a bit more settled.
