Brown 'freckles' on H.Polysperma leaves

[scottward]

It would appear that all my plant related problems are showing up on my Hygro Polysperma; I guess this is why it's an indicate plant.

I am thanking this plant though, of course. I guess this plant is helping me out really!

Anyway...my question....

I notice that there are brown 'freckles' on the leaves of my Hygro Polysperma. I am pretty sure that Tom has talked about this before as a CO2 related issue.

The freckles aren't turning into holes though.

CO2?

Here is a photo showing the brown freckles on the leaves.

Co2 for the go

No joking, if you dose EI as supposed, it is CO2/flow

My H. Polysperma shows this every time CO2 is on the low side. With the AM1000, for it to have a nice aspect, it needs a lime-green, quiet yellow at the end of the day. Otherwise, it rapidely shows those symptoms. Under high light, CO2 needs to be really optimized even more.

Under high light, it is an envading plant, needing a prune 2-3x/week. Under low light, it is a great 1-2x/15d pruning beauty, much more easier to deal with its growth and CO2

Thanks Jonny, I was pretty sure it was CO2, despite books saying that this is a nitrogen deficiency etc etc..... ;-)

Oh, upon closer inspection, the leaves are turning into tiny little holes!
