From looking at deficiency descriptions I think I'm short on Phospherus and possibly Potassium. I should have DIY CO2 up and running next week and stop using Excel.
Are P and K treatments universally recommended? From what I've gathered they're only needed in special situations when they aren't available in the water supply.
The progostemon and hygrophila (potted) have already lost 50% of their leaves and don't seem to be recovering.
You are going to need a more comprehensive fertilizer routine. the Florish I am guessing your using is Comprehensive? That contains only trace elements, you need the macro elements too with that much light, as well as good stable co2. Take a look here for a well used fert. routine. https://www.plantedtank.net/forums/fe...-regimes_.html
Yes, I'm using Flourish Comprehensive (and Excel). I've been told by several LFSs that adding macro elements is not needed...they don't do it and have good growth using tap water.
Yeah, I say cut back on light and dose more completely (make sure to cover nitrogen, phosphorus, potassium, and traces)
I've cut back to a single 24W bulb and no change in plant health. Only less algae growth.
Your substrate sucks, get one that's more appropriate for growing plants. ADA Aqua Soil, Flourite, Eco-Complete. Switch it out and you're good.
I've considered it, but only as a very last resort. Many of my plants aren't root feeders so substrate shouldn't be much of an issue (I think).
Also with your substrate Dont gravel vacuum it either. Let the detritus and stuff build up in the gravel. Doing so also helps make your substrate a better performer then what it is.
I did a big gravel cleaning just before planting the new batch, but there's still plenty of crud in there.
How old is this tank setup? Very often new plants die off due to being grown immersed at the nursery and need adjustment time being submersed when you put them in your tank. Could it be that?
1 year old. Java fern, Anubias, Wisteria, and Swords were planted then...Wisteria died fast, the rest keep limping on. The other plants are 1 month old and were shipped cross country (arrived in great condition) so maybe you're right that they need to adjust.
