The first thing I noticed is your light intensity.
It is difficult to judge from a photo because your lens may not be showing the real intensity. However, If you dose EI and you still facing nutrient deficiency, light intensity is an element you should consider.
It can be so high that drives plants to require even more nutrients. If I was you, I would keep my light intensity at a medium level and I would keep dosing EI. Having extra nutrients in water column will not cause any harm.
What I have learned during my short aquascaping journey is that the best you can do is to limit your light. The most common perception among newcomers or even more experienced hobbyists is that plants need tons of light to grow. This is not true. They just grow faster and you take the risk of having algae and instability problems.
Yea i lowered it now to medium (i think ? how do you determine this.) i also watch alot of youtube channels like green aqua etc, and they always have their lights on 100% and theyre tanks look amazing.
when i looked at a review about these lights they did a PAR reading and it wasnt so much for 1 bar, so i thought i needed to put the light on 100% as i also saw in other video about a guy with the 1500 series of juwel helialux spectrum, and his tank was doing great, he was even growing cryptocoryne flamingo. AQUARIUMS for me atleast hightech is a big puzzle. and i wont give up 😛
