help my nanas!

[Cardinal Tetra]

found some spots on the leaves of all my nanas, seems to be like some sort of nutrient difficiency. the pigments of the spots looks like they're melting, and sort of transparent in colour. in other words, the spots are not as colourful as the leaf, and looks like its transparent/melting.
dun get the wrong idea, the leaves are not melting, its those spots that make a leaf with melting holes. i quickly added a dose of liq fert.

5g tank
ph 6.1
temp 29'C
inmates: rummynose, yamato, badis,otto
light 18W

could it be a sign of insufficient lighting? my 2ft tank has the same problems too, the nanas are almost filled with melting holes.

i managed to find a very bad pic of how it looks like, and here it is.

look at the leaf on the right directly below the neon tetra. it appears to be a black spot there. however my leaves are covered with them, whereas that sword leaf only shows a single spot.

Slower growing plants like nanas are usually the last to show deficiency.

Transparent portion of the leaves may indicate the plant may be rotting at the roots. Do take the plant out and inspect.

okok.... this is the detailed syptom of the leaves after close inspection.
it looks like when you boil a leave in hot water, some pigments will turn darker..... that's what happening to my leaves. there are dark green spots on the leaves around 1mm in diameter.... whats happening? pls i need help

Could be spot algae. Dose it only appear on leaves or parts of leaves that are not shaded?

[Cardinal Tetra]

the leaves are shaded and unshaded.
it only appears on my anubias leaves. the strange thing is that the newer leaves have little or none of these spots. spot algae? i've never seen it b4... do you have a pic of spot algae? how do i get rid of it?

[bclee]

Vinz is correct. Likely to be algae. Anubias are prone to those algae.

the spots on the leaves are similar to mine.

nana's are very prone to intensive light as said , a shaded place will be an ideal condition where they will thrive =) hope this info helps
