Hi, This tank has been planted for about 2 weeks now.
20G
CO2
Light on for 7 hours daily (split: 3 ON, 2 OFF, 4 ON)
EI Dosing
50% water change weekly

Recently my S Repens have started to get dark green spots on the leaves, should I be worried or is this normal for the older leaves? These were clippings btw.
Not diatom as I am not able to rub anything off the leaves.

Thanks. It does look like GSA. Seems to be all contained on the plants, none on the glass yet.

I am dosing via EI, it's odd that I would have a shortage of phospates. My photoperiod is not too long and I have enough CO2 in solution according to my drop checker (indicator matches the reference almost exactly).

I added some root tabs under the plants, hopefully that will help them. I have been dosing ferts in the water column for only a week though, the first week there was no ferts added.

These plants were mostly clipping without roots when they were planted.
They have not gotten any taller since I planted them about 10 days ago.

This is how they looked when I got them:

Tank has eco complete with gravel cap.
