Default plant deficiencies please help

hello APC,
so lately I've noticed paler growth, testing of the leaves, and they are stubby and smaller. more noticeable on the polysperma (edit: I'm starting to think it could be a. reineckii) and palustris.
the tank was dosed yesterday the the macros are a tad high.

ammonia:0
nitrite:0
nitrate:15-20ppm or so
phosphate:5 ppm

dosing:
kno3 3.5g every 3 days
kh2po4 .5g every 3 days
flourish iron 3.5 ml every 3 days, day after macros.
flourish trace 2 capfuls every 3 days

lights:
2x54 8 hours
4x54 2 hours midday

any ideas?

It looks like iron deficiency, even though you are dosing iron.

I don't think that can hurt anything. Try it.

dosed an extra 2 ml of iron new growth is still looking the same.
could it be Ca deficiency? I'm sort lost here. tried upping the co2 but an hour later the fish are gasping, so I think I'm sitting pretty close to threshold for them. any suggestions?

Can't be calcium deficiency which is characterized by distorted, crippled, smaller, new leaves and then death of the growth point (meristem).

sort of sounds like what happened to my m.filigree in my 10 gallon a while ago. the stems blackened mid stem and broke off and rotted away. other plants started getting really small growth and one by one all my stems started blackening and dying.

anyways, I put flourish root tabs in and the plants are looking healthier now. however, I'm getting green water now

You need to test your GH or do you know it? With your current fertilizing I would suspect a deficiency in Ca or Mg, more specifically an imbalance. Is your water extremely soft? What is your Kh?

I use my tap, last I remember it was 3-4kh and about 8-9gh. root tabs aren't helping. my green nesaea is having twisted tiny new growth but are consistently green.
