What are these plants trying to tell me?

[PaphLover]

Phrag. Ingrid Portilla




NOID Brassidium


The phrag was on a heat mat under a T50 light.

The brsd in my living room window.
Both in semi-hydro.

I suspect they both might be from over-fertilizing.
I do tend to have a difficult time not feeding my plants at every watering.

I do flush with either tap water and then rainwater or soaking in rainwater (it's difficult to 'flush' with rainwater as I live in condo and only have a few milk jugs full) before refilling reservoirs.

Thanks for your input!
