I stand by probably not K from what you describe. Im leaning towards phosphate. Did you look up pics of K deficiency?
You know what.. I just realized you haven't told us about your lighting. Type of bulbs, wattage, color temp, age, etc. The more you describe what's going on, the more I want to suggest a possible lighting issue rather than a nutrient issue. I just don't see how, after only a month, and with dosing flourish twice a week, that you're already seeing deficiencies. Most of the time, K and P deficiencies are only an issue on co2 injected, higher light tanks. Not always, but usually.
Hmm, could increas water temp and aquarium salt have any effects?
Absolutely. I melted a couple of my plants when I brought them temp up to treat ich once, and I didn't even use salt.
Might just need to wait this one out. I the mean time, maybe up fertilizer just in case. And because you have a fairly high-tech system going, consider dry ferts. Gives you a little more control and helps identify deficiencies, IMO and IME.
Oh dear, here's your problem.
Your lights are driving an intense need for nutrients. What we're seeing is probably a combination of multiple deficiencies. If you have CO2 and T5HOs, you need to have good ferts available. I HIGHLY recommend you get some dry ferts. It will be about $25 shipped and will last you a year+. Your plants will go link gangbusters afterwords.
Root tabs are a supplementary fertilization. Water column should be primary. Your wisteria will go BANANAs.
epiphysis said:I use basic stuff you find at pharmacies since we don't have any specialised ferts available appart from the Seachem range.
KNO3, KCl and Lenolax (for phosphates) works for macro-nutrients. Should not work out more than $5.
I use Green Leaf Aquariums. You can just get their complete package or w/e its called for $20 plus shipping. Then you need to determine a dosing strategy and read up on it. Pps is popular, but I like EI myself.

I'd agree. I was thinking you had a low light tank going off the plants you have.
okay, that sounds more than plausible. I know you mentioned it in some other post but i can't find it from searching your name but what are some "quality dry ferts" and where do i get them?
Until then, i will probably use one light in lieu of two thereby cutting my light in half since I they are on separate switches. the question then becomes which to use/not use. Flora Sun or Ultra Sun
