Can anyone spot the deficiencies in these pictures...
I know why I have them, it is because I switched from 75W to 10W of lighting and haven't upped my dosing enough to compensate. I vaguely think it is a macro shortage - nitrates and phosphates, maybe potassium as well, but would appreciate some second opinions. I know it is good to know all the tank stats so I have put some details at the end of the post. I also know it could always be CO2 (I don't have a drop checker), but I *think* I am OK there, as my reactor is right next to the plants in question and it is a relatively small tank...

Tank Stats
Old Lighting - no signs of deficiencies
3 x 24W T5 Triplus.
Upgraded to:
3 x 24W T5's (1 Grolux and 2 Osram 880's).
Due to the luminaire shape the light covergae wasn't quite as even across the tank so I plumbed in one of the T8's again.
So I am now running nearly 100W of lighting:
1 x 25W Triplus T8
3 x 24W T5's (1 Grolux and 2 Osram 880's).
Observations
When on 75W plants showed no obvious signs of deficiencies.
On 100W I noticed a bit of spot algae, so I doubled my phosphate dosing.
Now 10 days in (ish, I never was good at keeping track of time) my Amazon swords have holes rapidly appearing in them. The leaves in the light have gone a lot lighter and the leaves in shade have gone a lot darker!
My hygro has also got holes in the older leaves which are disintegrating.
All the other plants are loving it, especially the java ferns which are pearling like good uns
Other tank stats
Size
36" x 20" x 15"
Water column apprx 160l~42US gallons~35UK gallons
Fertilisation
CO2
Pressurised with Barr venturi style reactor, apprx 1/1.5bps.
Dry ferts
Macros and Nicros dosed on alternate days:
Macros
0.4 tsp of KH2PO4 (very apprx)
1 tsp of K2SO4
1 tsp of KNO3
Micros
1tsp of PMDD mix (equal parts: CSM+B,MgSO4,K2SO4,NN03)
1 tsp of MgSO4·7H2O (added once a week after water change)
50% water change weekly.
Clean internal power filter monthly.
Remove dead leaves etc from the tnak as and when, but usually weekly.
I'm on top of tank maintenance, so don;t think it is that.
I am happy experimenting with upping my dosing, just thought I'd get some second opinions...
