Did you play with the light intensity recently? Or position adjustment

My MC has been spreading well until 2 weeks ago.....
I began to notice certain portion is turning transparent (is this what ppl called Chlorosis?) .... And the effect is spreading slowly to a wider and wider area....

Been dosing
- K 1.5ppm daily
- P 1.0ppm bi-daily
- N 2.5ppm bi-daily
- Lushaqua Micro 3 drops bi-daily
(my Micro trace is pretty mild
Fe 0.0106ppm
Mn 0.0028ppm
B 0.0002ppm
Zn 0.0003ppm
Cu 0.0001ppm
Mo 0.0002ppm)
- FE 0.005ppm every 4-days
Lights: Zetlight 6300 with 8 hrs daylight (Level 24 intensity)
CO2: On and Off 1 hour before daylight.
Qns:
1) Anyone knows what happened?
2) Should I remove all the affected portion?

I did change a light, but that was abt a month ago, things was doing fine, until 2weeks back MC began to turn transparent, and only that portion...Originally Posted by milk_vanilla
Will Excel nuke caused this to happened? The only thing I recalled is nuking the BBA on my S.Repen and AR.Mini, which is near to the affected MC. I have 100L of water, biking with less than 2 caps of Excel for 3 days.

I reckon it's the Excel. I spot treated my MC with diluted Excel for GSA, and the affected area started melting a few days later.
Thanks Ivan. Do I need to remove the whole affected area? Or just leave it?

Previously I allowed the MC to 'cover up' damaged/algae infested areas, which lead to more problems down the road. Damaged/algae infested leaves will eventually rot and hurt water quality. Now I aggressively hack away any damaged portions, the MC will creep and cover the gaps in no time, don't worry!
Don't sweep things under the 'carpet' (pun intended), my lesson learnt!
Ok noted, will do some maintenance this weekend

Slightly off topic - a better way to deal with BBA is to bump up the CO2 bubbling rate and increase flow. It works, if you intervene early.
Thanks.
I did add a Powerhead to increase the flow, BBA is kinda under control now.
But I can't increases the CO2 bubbling rate because of CRS
