How Much Ferts For Just Crypts With Co2 Injection?

I don't know how much to dose N P K, Micro ppm in my 150 liter with just Crypts??

I'm using a Twinstar 900s it's on for 7 hours -- a CO2 reactor it starts 1 1/2 hrs before lights on and turns off 1 hr before lights off.

I'm dosing daily 3ppm KNO3, 1ppm KH2PO4, 1ppm K2SO4 and .2ppm CSMB+
50% WC once a week.
Front load after the WC. 9.375ppm KNO3, 1.5ppm KH2PO4, 3.375ppm K2SO4 and 3.75ppm MGSO4 and
.2 ppm CSMB+

Before I went to just having crypts only in the tank I had a lot of high light plants. I'm still using the same amount of ferts, light duration and CO2, so I definitely think I'm over dosing and the CO2 is probably too high as well. It's about 50ppm

I'm seeing a lot of hair algae on the leaves. I know these aren't fast growing plants. I'd like to try a shorter photo period with a lower light intensity less CO2 and lower the dose amounts.

I'm trying to go with the less is more approach and cut down on maintenance. The Crypts are growing quite well, despite the algae. My phone doesn't take pictures very well, I hope it's good enough?

I'd really like to get the ppm per dose worked out.. I always seem to have problems with dosing. For that matter, CO2, Light duration and intensity... So pretty much everything. I just can't seem to get this worked out.

I hope someone can help me??
