Quick shot to update progress.
Was getting a few signs about low co2, so knocked the lighting period back a bit to 6.5 hours, dosed a bit less.
Then a few leaves started yellowing, so upped the dose a bit more.Have been trying out a TPN+ clone with dry salts but not sure i've got it quite right, so i'm going on the TNC bandwagon.
PH has started to drop a little now that i've eased back on the daily waterchanges.Doing 2x 50% a week.
Some of the Baccopa at the back is a bit leggy but going to let the new growth come on a bit before i trim and replant.
Everything else just growing in a bit really.Think i've got the flow right with the spraybar just angled down.It hits the far side & rolls back.The lotus sways, but not the Pogostemon.However it is growing and the lower leaves aren't shedding.
I can now see the benefits, of planting more densely than i have.There's a few more gaps in each area than i'd like.i'll just keep trimming & replanting.Just might take a bit longer to get there.
