Nutrient deficiency?

Sorry if this is in the wrong place, it's my first post here.
I have a 36 gallon low tech tank with a rosette sword and some crypt wendtii that seems to have a nutrient deficiency.
Lighting is 2 22" (I think) t5 ho lamps
The sword's older leaves are turning a mottled yellow one by one while the new leaves are stunted and slightly wrinkled, though still completely green.
The crypts older leaves are dying one by one and after death have dark green stripes running across the leaf that is definitely not algae.
Both plants are next to api root tabs that are less than 2 months old (though they were in the packs for a long time before that) I also add about 3 ml of flourish comprehensive after my weekly pwc's
I don't have time to post pics right now or test water params but will do so later tonight if requested.
What is going on and how do I fix it?

Crypts typically put roots up into the water when they don't get enough nutrients.

I think excessive nutrients might be the problem. Check nitrates and ammonia. It would also be good to know the other parameters to make sure nothing is way off.

What kind of substrate do you have?
