rotala blood red is blotchy?

@dIggO
Keep us posted on the progress of the Rotala.
Out of curosity how are you dosing the fertilizers when adding them to the aquarium?
 
Thank you, I will keep you posted!
I'm dosing as prescripted via the solutions made from dry salts in the EI package delivered by PlantedBox.
@Happi : The trace elements are not csm+b according to the seller. The Potassium phosphate is KH2PO4.

Are you dosing straight into the water column?
If you are, best mixing the fertilizers with a jug of aquarium water.....then tipping it in.
Rotala are very susceptible to leaf burn if the fertilizers are dosed too near them.

No, premixing it with distilled water as described by PlantedBox.

Yes, Indeed.....
Add to the aquarium water column not in the vicinity of the Rotala Blood Red!

Always in the stream of the outflow. The Rotala is one of the last to be "hit".
 
OK, here's what I could find out.

So the right collumn (30ml) is my weekly dose for the tank. But how do I convert that to N, P, K, Mg etc in ppm?
And what do I need? (as a guideline)

I'm sorry if I'm asking too much, but I'd like to master this and do it right!

(Sjeezz, BBCode is ugly...😳)

A calculator like above is the easiest way of doing it.
Your salt weights indicated in the 30ml column are adding weekly.
No3: 18.77 ppm or N: 4.24 ppm
K: 12.78 ppm
Po4: 2.3 ppm or P: 0.75 ppm
Mg: 1.81 ppm

Can't work out levels of Fe or trace mix without knowing for sure the exact composition of them. Eg: dtpa 7%, dtpa 11%.
 
After 2 times a 50% water change and trimming of the Rotala there is some new "better" growth. Defenately less coloring and especially the centers.
I also notice a significant increase in green thread or hair algae. Balance was off as a result of stopping with ferts I guess. The light will have to be dimmed a bit, or can I start fertilizing a little? (@G H Nelson: asked carefully, since you asked for a 4 week stop period)

Hi
Continue with water changes and dose 25% of the recommendation.
New leaves need to mature before colour increase's.
Green thread algae = too much light usually?

Will do 25%!
"Green thread algae = too much light usually?" Yes, but I didn't change anything, but stopping ferts. So I think the balance was off because of that. Now I turned the light a bit down and the CO2 up.
 
Hi there!
I promised to keep you informed. Wel, it turned for the better! All new growth on the Rotala is looking much better now. Although they look a bit thin (longer internodes). Can that be a result of less ferts?
I'll attach a pic later on when the lights are on.

As promised the pic:
