Dear all,

I need some advice on which part of the PMDD fertilizer I should increase.
My tank specifications:

240 l.
Light: 162 Watt T-5, Arcadia plant pro
DIY CO2, approx 3 bubbles per second

I can currently not provide any water values since I do not have any water tests.

I have recently been experiencing that my Glossostigma leaves go white/milky as in this picture:

Here is a picture to show the amount of plants I have:

My PMDD dosage (maybe a bit odd from how you are used to dose)

I mix below in 400 ml of water, then I dose 14 ml of this mixture daily:

33 g - MgSO4
14 g - K2SO4
6 g - KNO3
15 g - Tenso cocktail - Fe, B, Ca, Cu, Mn, Mo and Zn

I would like to keep dosing daily since I keep Discus and they become very nervous when doing 50% water changes, which I understand
has to be done when dosing PMDD on a weekly basis (to reset the water values)

As you can see I dont dose any KH2PO4, is this the problem?

I would really appreciate your comments and advise.

Regards

Joshua

Try dosing some KH2PO4 and see.
Dose in the AM, come back later that day and see the plants.

Thank you for your reply, I did dose approximately 3 g yesterday, what amount of KH2PO4 is safe to dose?

That means I dosed 3 g to the 400 ml water solution with fertilizers, I did not dose 3 g directly in to the Aquarium water...
