Had a go at doing a micro eco bowl with Walstad method but its all gone south so far... ?

Bowl: 1.5g when filled to brim with water.
Dirt: 1" of Miracle-Gro organic choice vegetable & herb mix. (couldn't find the potting mix here in Australia).
Gravel: 2~3mm inert.
Light: 9 watt cfl about 1 foot above the gravel.
Temperature: Steady at 26°C. The big ass heater is just temporarily in there.
Plants: Water sprite, Thin val, Narrow leaf Java fern and Java moss tied to a small lava rock, Banana Lily and Frogbit.
Day 1: Layered with dirt, topped with gravel and did 2x90% wcs without Prime (probably a mistake, could've killed all the bbs in the soil). Used Prime since.
Day 2: Ammonia 0.5ppm, 90%wc with Prime and planted;
2 water sprites
3 thin vals, roots thinned and trimmed shorter to suit the height of the bowl.
1 bunch of Java fern and some java moss tied on a small lava rock.
1 Banana lily, had only few small leaves but good stack of nanas.
4 rosettes of frogbit.
All plants were healthy overall.
Day 3: Ammonia 1ppm, 90% wc.
Day 4: Ammonia 2ppm, 90% wc, all plants looking yellowish, frogbit loosing roots.
Day 5: Ammonia 3ppm, 2x 90%wc (morning & evening). Vals all melted and droopy.
Day 6: Ammonia 4ppm, 2x 90%wc, added Seachem Stability and flourish, water sprite and banana lily all leaves melted and frogbit and moss partially.
Day 7: Ammonia 2ppm, 1x 90%wc, Seachem Stability and flourish, new buds on water sprite and frogbit.
Day 8: Ammonia 1ppm, 1x 90%wc, Seachem Stability and flourish, new growth on water sprite has brown cuts & spots, frogbit and moss show new growth.
Day 9: Ammonia 0.5ppm, 1x 50% wc, Seachem Stability and flourish, moss seems dull and holes in Java fern, frogbit old leaves melting. Whitish webs and brown spots on the bananas.
Today: Ammonia 0.25ppm, no Stability but flourish added, no water change, growth on water sprite gets bigger but still looks damaged, frogbit staying light green and recent leaves yellowish at the edges while the older melts away, java moss n fern still struggling and vals seems completely smashed.
Although Stability has greatly reduced and consumed the ammonia being produced, a cycle still hasn't been established as I haven't seen any nitrites or nitrates yet. PH 6.8~7.0, kh & gh 2~3, similar to tap water.
Any thoughts on how to make this bowl survive and thrive would be great... thanks!
