Joe,
Try growing some floating Hornwort to shade the unplanted patch until you get some other plants to replace that empty patch.
Tank size: 45 x 30 x 30cm (41litre / 11 gallon)
Lightings: 55W
Duration: 9am to 4pm
PH: 6.6-6.8
KH: 4.0
Plants: Lobelia Cardinalis, Hygrophila Compacta, Rotala Wallichi, C.Parva, C.Lucens, Xmas Moss, Narrow Leaf Java Fern
Fish: 8 rummy-nose tetras, 4 cories, 4 pencil-fishs, 3 otos & 10 shrimps
Fertilisation: No base fertlisers.
1/8 teaspoon KNO3, 2 small grain PO4, 4ml Seachem Fluorish twice a week (once Monday morning after 50% water change, once Thurs morning before weekend)
Issue:
Before this, there was not much issues as I had a lawn of thick glosso. I was dosing 1/4 teaspoon KNO3, 4-8 small grain PO4, 4ml Fluorish twice a week then.
With the glosso lawn removed, green algae is appearing on the gravel everywhere. More spot algae are also appearing on the walls. There was some BBA but this has subsided quite a but after manual removal and pumping up the CO2. I reduced the dosing to 1/8 teaspoon KNO3, 2 small grain PO4, and started adding 0.25 tsp K2SO4. Flourish still remains at 4ml twice a week. The green algae on the gravel is still there after 2 weeks. Any comments on how to proceed to remove the green algae?
I know the lightings is kinda high and most of the plants are slow growers :P
Joe,

Resistance is futile, you will be administrated!
No base fert, but are you using root tabs, sticks, etc?
How old is the tank/substrate?
How much of your substrate was covered with glosso? How thick was the glosso lawn? Were they algae free and growing well?
Fish load?
Could be the uprooting of the glosso brought up a lot of mulm, etc. Have you cleaned your filter since then?

Why use punctuation? See what a difference it makes:A woman, without her man, is nothing.
A woman: without her, man is nothing.
geoffrey, later am gonna get some frogbits later tonite to suck up more nutrients and provide some shade.
vinz, acutally there is baser fert but only like less than 0.5cm thick ... root monsters and laterite balls are inserted at where the plants are
The whole tanke is probably 6-8 months old and 40-50% was covered with glosso 1 inch thick. Algae was quite minimal that time but now the green algae is coming back fast and furious even though I have manually removed a fair bit of the infect gravel. Lots of mulm was dug up but the filter has been washed many time since
Dun tink my bioload is hight right?
Main issue here...too much light and too many critters. You don't need that much light to grow plants. If you fancy high light tanks, go for 3w/g at most unless you know what to do. The more the light, the more the demand on CO2 and nutrients. Things move so fast that a moment of mistake and you crash the whole tank. For such a small tank, you are keeping a critter load more suitable for a 30-40gal tank and that will be an issue when your plants and filter does not work well.
Before you try the routine I suggest for you, you might want to consider dropping the lights and critter loading.
70% water change once a week or better 2x a week
Prune and remove all possible dead looking leaves and algae
Clean the filter if necessary
Slightly less than 1/16tsp of KNO3 3x a week
2 rice grain of KH2PO4 3x per week
2ml of flourish 3-4x a week
Main thing is to keep up on the CO2. Try to target a pH of 6.6-6.7(max)..
Add more fast growing plants to the tank as well...keep the plant mass as high as possible at all times.

Will try to reduce to 36W to see how it goes but can't help with the bioload. Will this affect the balance a lot? I feed them usually only once a day on weekdays and none on weekends since this tank is in the office.
36w is fine but an office tank is better with 20w. Slower growth and you can get away with things if you forgot to dose. But the main issue is the critter loading. Like the critters? Give them a better and bigger space to live in. How about I throw your entire family into the storeroom for a week?

Heh frankly the otos and shrimps are usually nowhere to be seen. I get to see only the cories and a few tetras which come out for food
There was a calculator on the web previously, cant remember where saw it, that allowed you to estimate whats the right amount of fish for your tank size
Does anyone know where that can be found?
Maybe with that we can determine if its the bioload thats the main cause of it
